Mr. Abiy succeeded partly by mobilizing ordinary citizens to take up arms to block the Tigrayan advance. “Nothing will stop us. The enemy will be destroyed,”

Drones have also hit refugee camps in Tigray and killed dozens of civilians. Despite recent releases of political prisoners by Mr. Abiy, which prompted a phone call with President Joe Biden, the prospect of a cease-fire seems distant.

The Ethiopian military suffered a major defeat in June when it was forced to withdraw from Tigray, and several thousand of its soldiers were taken captive.

But after he took office in 2018, he set about draining the group of its power and influence in Ethiopia, infuriating the Tigrayan leadership, which retreated to its stronghold of Tigray. Tensions grew.

In September 2020, the Tigrayans defied Mr. Abiy by going ahead with regional parliamentary elections that had he had postponed across Ethiopia.

Two months later, T.P.L.F. forces attacked a federal military base in Tigray in what they called a pre-emptive strike against federal forces preparing to attack them from a neighboring region.

The conflict threatens to tear apart Ethiopia, a once-firm American ally, and further destabilize the volatile Horn of Africa region.

Through it all, civilians have suffered most. Since the war started, witnesses have reported numerous human rights violations, many confirmed by a U.N.-led investigation, of massacres, ethnic cleansing and widespread sexual violence.

In western Tigray, ethnic Amhara militias have driven tens of thousands of people from their homes as part of what the United States has called an ethnic cleansing campaign.

Tigrayans make up just 6 or 7 percent of Ethiopia’s population, compared with the two largest ethnic groups, the Oromo and the Amhara, which make up over 60 percent.

But at home, the Tigrayan-dominated government systematically repressed political opponents and curtailed free speech. Torture was commonplace in government detention centers.

Mr. Abiy, a onetime T.P.L.F. ally, moved quickly to purge the old guard. He removed Tigrayan officials from the security services, charged some with corruption or human rights abuses and in 2019 created a new political party. The Tigrayans refused to join.

At the same time, he strengthened his ties to President Isaias Afwerki, the authoritarian leader of Eritrea, who nursed a bitter, longstanding grudge against the Tigrayans.

But by mid-2020 that peace pact had become an alliance for war on Tigray.

Children are dying of malnutrition, soldiers are looting food aid, and relief workers have been prevented from reaching the hardest-hit areas, according to the United Nations and other aid groups. Since July, a government-imposed blockade of Tigray has kept desperately needed aid from reaching the area. In late November, the World Food Program announced that 9.4 million people across northern Ethiopia required food aid.

The T.P.L.F. was born in the mid-1970s as a small militia of ethnic Tigrayans, a group that was long marginalized by the central government, to fight Ethiopia’s Marxist military dictatorship.

Ethiopia’s ties to the United States, once a close ally, have come under great strain. Mr. Biden has cut off trade privileges for Ethiopia and threatened its leaders with sanctions.

He freed political prisoners, abolished controls on the news media and helped mediate conflicts abroad. His peace deal with Eritrea and its authoritarian leader, Mr. Isaias, caused the Ethiopian leader’s international profile to soar and led to his Nobel Peace Prize in 2019.

But even before the war erupted in Tigray, Mr. Abiy had resorted to old tactics of repression — shutting down the internet in some areas, arresting journalists and detaining protesters and critics.

In a stark speech in November, Mr. Abiy called on soldiers to sacrifice their “blood and bone” to bury his enemies in “a deep pit” and “uphold Ethiopia’s dignity and flag.”

“It’s completely unacceptable to spy on journalists,” said Carlos Dada, the founder and director of El Faro. “It endangers our sources, it limits our work and it also endangers our families.”

An El Faro journalist’s phone had been reinfected with the spyware over 40 times, the most persistent hacking attempt by Pegasus yet to be discovered.

Revelations that Pegasus software has been used to unjustly spy in El Salvador may not come as a complete surprise, but there is no match to our outrage.”

El Salvador’s government denied responsibility, and a spokesperson with NSO Group would not say whether Pegasus spyware had been provided to El Salvador’s governments, past or present.

“The government of El Salvador is investigating the possible use of Pegasus,”

a prized Israeli technology company whose spyware has long been under scrutiny for its ability to capture all activity on a smartphone — including a user’s keystrokes, location data, sound and video recordings, photos, contacts and encrypted information — and for mounting allegations of misuse by repressive governments.

The spokesman added that the company does not know who the targets of its customers are, but that NSO works to ensure that its tools are used only for authorized purposes.

The Biden administration blacklisted NSO Group in November, stating that the company had knowingly supplied spyware used by foreign governments to “maliciously target” the phones of human rights activists, journalists and others.

After the American government blacklisted NSO Group, the company promised that Pegasus was only licensed to governments with good human rights records.

But in December it was announced that the iPhones of 11 American Embassy employees working in Uganda had been hacked using Pegasus spyware.

In an emailed statement, a spokesperson for NSO Group, who declined to provide their name, maintained the company only provides its software to legitimate intelligence agencies and to law enforcement agencies to fight criminals and terrorists.

In August it was revealed that Pegasus had been secretly installed on the smartphones of at least three dozen journalists, activists and business executives across the world, including close associates of the murdered Saudi journalist Jamal Khashoggi.

The Israeli military has also been criticized for its human rights violations at home and abroad.

El Salvador has been criticized for intimidating and censoring local media.

El Salvador’s president, Mr. Bukele, has come under withering criticism from the United States government and rights groups for using the military to interfere with the legislature and to suspend Supreme Court judges and the attorney general.

it was because it had been used “for subversive purposes and criminal activities.”

In the now-deleted tweet, which was aimed at “those misbehaving,” Mr. Buhari said that the government would “treat them in the language they understand,” a message that was widely read as being a reference to the deadly Nigerian civil war. Some interpreted it as a threat of genocide.

In recent years Nigerian lawmakers have introduced several bills that, if passed, would regulate social media, arguing for them on the grounds of security or national unity. Rights groups say these measures — none of which have been approved — could violate international laws protecting freedom of speech.

“Our mission in Nigeria & around the world, is to serve the public conversation,” the post read. “We are deeply committed to Nigeria, where Twitter is used by people for commerce, cultural engagement, and civic participation.”

Twitter is far from the most popular social media platform in Nigeria — it is thought to have around three million users there and is ranked behind WhatsApp, Facebook and Instagram.

Many Nigerians who used Twitter to promote their businesses have lost revenue.

Beyond the economic consequences, there were also profound societal ones,

The Nigeria Center for Disease Control had been using Twitter to disseminate information about the spread of the coronavirus, she said. It was a go-to source for Nigerians seeking information about reported cases, deaths and tests. During the ban, the organization’s Twitter account was inactive. Its last tweet was a breakdown of cases by state from June 4.

The organization disseminated information through Facebook, but many Nigerians did not know this, even as the Delta variant was spreading.

“A lot of people didn’t fully get the impact of the Delta variant,” Ms. Adamolekun said, “because they weren’t getting the updates.”

“We are not indifferent to security objections voiced by participating states,” Mr. Rau said. “I believe that the O.S.C.E. is the right platform to discuss every aspect of comprehensive security.”

The exchanges at an international meeting left tensions high and the implicit threat of further Russian military intervention in Ukraine on the table.

While Russia denies it has plans to invade Ukraine, researchers have identified some new signs of Russian troops moving toward the Ukrainian border in recent days.

“The hard reality right now is that we were promised a written reaction,” Mr. Lavrov said in an interview aired on Thursday, according to the Interfax news agency. “We will wait for it. And then we will determine our next steps.”

“If we do not hear a constructive response on our proposals in a reasonable time frame,” Mr. Lukashevich said in remarks released by his office, “we will be forced to draw the corresponding conclusions and take all necessary measures to assure the strategic balance and removing unacceptable threats to our national security.”

To help fill the gaps, Taliban officials are reaching into Pakistan.

Now, the Taliban are privately recruiting them to return and work in the new government.

It is unclear how many former fighters have returned from Pakistan, but there have already been several high-profile appointments, including Mr. Ghayoor.

The new hires are walking into a mounting catastrophe. Hunger is rampant. Many teachers and other public sector employees have not been paid in months. The millions of dollars in aid that helped prop up the previous government have vanished, billions in state assets are frozen and economic sanctions have led to a near collapse of the country’s banking system.

“Running insurgency and state are two different things,” said Noor Khan, 40, an accountant who fled Kabul for Islamabad in early September, among hundreds of other Afghan professionals hoping for asylum in Europe.

Five months after their takeover of Afghanistan, the Taliban are grappling with the challenges of governance. Leaders promised to retain civil servants and prioritize ethnic diversity for top government roles, but instead have filled positions at all management levels with soldiers and theologians. Other government employees have fled or refused to work, leaving widespread vacancies in the fragile state.

Mr. Ghayoor, the baker turned police chief, said that Kabul changed markedly in the two decades that he was away. As part of his duties, he tries to instill order at a busy produce market in Kabul as vendors tout fruit and vegetables, and taxi drivers call out stops, looking for fares.

Sirajuddin Haqqani, head of the militant Haqqani network and labeled a terrorist by the F.B.I., was appointed acting minister of the interior, overseeing police, intelligence and other security forces.

“They have no experience to run the departments,” said Basir Jan, a company employee. “They sit in the offices with guns and abuse the employees in the departments by calling them ‘corrupt’ and ‘facilitators of the invaders.’”

Taliban leaders blame the United States for the collapsing economy. But some analysts say that even if the United States unfreezes Afghanistan’s state assets and lifts sanctions, the Finance Ministry does not have the technical know-how to revive the country’s broken banking system.

“Their response to the catastrophic economic situation is ‘It’s not our fault, the internationals are holding the money back.’ But the reality is that they don’t have the capacity for this kind of day-to-day technical operation,”

Foreigners intentionally evacuated Afghans, most importantly, the educated and professional ones, to weaken the Islamic Emirates and undermine our administration,” Mr. Hashimi said.

“We are in touch with some Afghans in different parts of the world and are encouraging them to return to Afghanistan because we desperately need their help and expertise to help their people and government,”

Then as now, the Taliban preferred filling the government ranks with jihadis and loyalists. But this time, some civil servants have also stopped showing up for work, several of them said in interviews, either because they are not being paid, or because they do not want to taint their pending asylum cases in the United States or Europe by working for the Taliban.

Mr. Ghayoor said in December that neither he nor any other member of the Kabul police force had been paid in months. Nevertheless, he said he decided to sell his bakery in Quetta, a city in southwestern Pakistan, and move his extended family, including nine children, to Kabul.

Mr. Raslan’s guilty verdict, they say, bolsters the ability of European courts to pursue similar cases while sending a message to war criminals around the world that they could one day face consequences.

This sends a clear message to the world that certain crimes will not go unpunished.

After more than a decade of war, Mr. al-Assad remains in power, and there appears little chance that he or his senior advisers or military commanders will stand trial soon.

Other potential avenues for justice have also been blocked. Syria is not party to the International Criminal Court in The Hague, and Russia and China have used their vetoes on the United Nations Security Council to prevent Syria from being referred to the court.

He fled Syria in 2012 after the government committed a massacre in his hometown, killing more than 100 people. He joined Syria’s exiled opposition and traveled with them to peace talks in Geneva in 2014.

German prosecutors argued that his position gave him oversight of torture that included beating, kicking, electric shocks and sexual assault. Witnesses in the trial said they were fed inedible food, denied medical care and kept in overcrowded cells.

He entered Germany on a visa in 2014 and lived there legally until the German authorities arrested him in 2019.

But his past caught up with him in Germany, where he was tried for crimes against humanity.

When the Syrian conflict broke out in 2011 with protests seeking to topple President Bashar al-Assad, Mr. Raslan was the head of interrogation at a security office in the capital, Damascus.

Beatings were common, the food was inedible, the cells were so crowded that some prisoners had to stand so others could lie down. German prosecutors said at least 4,000 people were tortured and nearly 60 killed under his authority there.

The verdict marks a watershed moment for an international network of lawyers, human rights activists and Syrian war survivors who have struggled for years to bring officials who sanctioned or participated in the violence to justice.

He was arrested in 2019, and his trial began the next year. On Thursday, Mr. Raslan was found guilty of crimes against humanity and was sentenced to life in prison.

When Mahran Aoiun heard that a former Syrian intelligence officer had been sentenced on Thursday to life in prison for overseeing torture at a detention center, it brought back the joy he felt years ago when he was released from a brutal Syrian jail.

The verdict handed down by a court in Koblenz, Germany, against the former officer, Ansar Raslan, stirred complicated feelings among Syrians who were abused in Syrian prisons — some at the hands of Mr. Raslan himself.

Others hoped that Mr. Raslan’s conviction would draw attention to the many more crimes committed during the Syrian war that have not been prosecuted, and to the officials who committed them who are still free.

“Those who are torturing prisoners will think twice after the trial,” he said. “This is an achievement.”

New York Times photographers have covered Syria’s civil war and the humanitarian crisis it has unleashed since the uprising against President Bashar al-Assad began nearly 11 years ago.

Owing partly to its own history in World War II, Germany has become something of a go-to venue for prosecuting crimes against humanity, even if committed outside its own borders. It is also home to hundreds of thousands of Syrian refugees, putting it at the center of efforts to hold the government of President Bashar al-Assad of Syria accountable for war crimes.

German prosecutors built their case with the help of hundreds of Syrian witnesses in Germany and beyond. They indicted Mr. Raslan using “universal jurisdiction,” a legal principle stipulating that in the case of crimes against humanity and genocide, normal territorial restraints on prosecutions do not apply.

The principle is not new. Israel used it during the 1960s trial of the former Nazi official Adolf Eichmann, as did Spain in 1998 when demanding that Britain arrest Gen. Augusto Pinochet, the former Chilean dictator. Previous universal jurisdiction cases in Germany have dealt with crimes committed in Rwanda and the Democratic Republic of Congo, and, more recently, with the genocide of Yazidis in Iraq by former members of the Islamic State.

Germany has the legal basis to prosecute such crimes under the German Code of Crimes Against International Law, which came into effect in 2002, and it has been using it.

“For Germany, it’s also historically the continuation of what we learned from the Nazi period and what we learned about the importance of the Nuremberg trials and the Auschwitz trials for the way we dealt with our past and ultimately for who we are today,”

The Nuremberg trials went after the leading members of the Nazi regime, but also a range of individuals who played a role in Nazi repression, including doctors, business leaders, bureaucrats and propagandists, said Wolfgang Kaleck, a founder of the European Center for Constitutional and Human Rights, which is representing victims in Mr. Raslan’s trial.

Raslan is the first ranking Syrian official to be convicted of war crimes, but he may not be the last.

But several other cases have already been tried or are pending.

A Syrian doctor accused of torturing a detainee in a secret military prison will soon go on trial in Germany on charges of crimes against humanity and causing grievous bodily harm. The doctor, Alaa Mousa, was living in Germany as a refugee when he was arrested in 2020.

Human rights lawyers concede that so far, the trials have targeted low- and middle-ranking Syrian officials or soldiers.

“If you don’t start now, then in 10 years, you cannot get Assad or his chief of intelligence because you have no evidence,” Mr. Kaleck said. “These cases are a way of building a stock of documents, witness statements, of understanding interconnections and gathering knowledge on which you can build future cases.”

Since the Syrian uprising in 2011, Syrian victims, human rights activists and others have filed more than 20 legal complaints against Syrian regime officials for war crimes and other violations of international law, according to Mr. Kaleck’s center.

This body of evidence, which has been growing for over a decade, could be used in different cases.“More has to come, that is clear,” Mr. Kaleck said. “But this is an important step.”

But the decade-long conflict has left the country shattered, killing hundreds of thousands of people, forcing half of the population from their homes and reducing major cities to rubble. Most of those who remain have been left to live in poverty.

The rebellion that began in 2011 as an uprising against Syria’s autocratic president, Bashar al-Assad, escalated into a civil war, but the splinted rebel movement failed to topple the government.

But the war was gruesome. The government employed poison gas, barrel bombs and suffocating sieges on rebellious communities, and waged a ruthless assault on civilian opponents, throwing hundreds of thousands into filthy prisons where many were tortured and killed.

Some Arab countries have begun restoring ties with the government in an effort to move past the war, although strict sanctions by the United States and other Western countries have blocked most investment.

The United States initially provided covert military support to the rebels, but as the war splintered into multiple overlapping conflicts, America shifted its focus to fight the jihadists of the Islamic State, who at their peak controlled nearly a third of eastern Syria.

For Syrian civilians, there is less daily violence now than during the war’s earlier years, but the economy has been destroyed.

More than half of Syria’s prewar population fled their homes during the fighting, and most have not returned, including the 5.6 million refugees who largely live in destitution in neighboring Arab countries.

“Justice has not been fully accomplished,” he said. “This is a small slice of what we are talking about.”

It’s working and it looks normal. We are thrilled, but we don’t know what tomorrow will bring us. This has never been done before

Last year, some 41,354 Americans received a transplanted organ, more than half of them receiving kidneys,

But there is an acute shortage of organs, and about a dozen people on the lists die each day. Some 3,817 Americans received human donor hearts last year as replacements, more than ever before, but the potential demand is still higher.

Researchers hope procedures like this will usher in a new era in medicine in the future when replacement organs are no longer in short supply for the more than half a million Americans who are waiting for kidneys and other organs.

He is also being monitored for infections, including porcine retrovirus, a pig virus that may be transmitted to humans, although the risk is considered low.

But he added that there were many hurdles to overcome before such a procedure could be broadly applied, noting that rejection of organs occurs even when a well-matched human donor kidney is transplanted.

It takes a long time to mature a therapy like this.”

Mr. Bennett decided to gamble on the experimental treatment because he would have died without a new heart, had exhausted other treatments and was too sick to qualify for a human donor heart, family members and doctors said.

Mr. Bennett is still connected to a heart-lung bypass machine, which was keeping him alive before the operation, but that is not unusual for a new heart transplant recipient, experts said.

The new heart is functioning and already doing most of the work, and his doctors said he could be taken off the machine on Tuesday. Mr. Bennett is being closely monitored for signs that his body is rejecting the new organ, but the first 48 hours, which are critical, passed without incident.

It is the first successful transplant of a pig’s heart into a human being. The eight-hour operation took place in Baltimore on Friday, and the patient, David Bennett Sr. of Maryland, was doing well on Monday, according to surgeons at the University of Maryland Medical Center.

Xenotransplantation, the process of grafting or transplanting organs or tissues from animals to humans, has a long history. Efforts to use the blood and skin of animals go back hundreds of years.

In the 1960s, chimpanzee kidneys were transplanted into some human patients, but the longest a recipient lived was nine months.

In 1983, a baboon heart was transplanted into an infant known as Baby Fae, but she died 20 days later.

Two newer technologies — gene editing and cloning — have yielded genetically altered pig organs less likely to be rejected by humans.

the time to carry out better screening for infectious diseases, and the possibility of a new organ at the time that the patient needs it.

The heart transplanted into Mr. Bennett came from a genetically altered pig provided by Revivicor, a regenerative medicine company based in Blacksburg, Va.

The pig had 10 genetic modifications. Four genes were knocked out, or inactivated, including one that encodes a molecule that causes an aggressive human rejection response.

A growth gene was also inactivated to prevent the pig’s heart from continuing to grow after it was implanted,

In addition, six human genes were inserted into the genome of the donor pig — modifications designed to make the porcine organs more tolerable to the human immune system.

The team used a new experimental drug developed in part by Dr. Mohiuddin and made by Kiniksa Pharmaceuticals to suppress the immune system and prevent rejection.

“The anatomy was a little squirrelly, and we had a few moments of ‘uh-oh’ and had to do some clever plastic surgery to make everything fit,”

“the heart fired right up” and “the animal heart began to squeeze.”

He said his father had had a pig’s valve inserted about a decade ago, and he thought his father might be confused. But after a while, Mr. Bennett said, “I realized, ‘Man, he is telling the truth and not going crazy. And he could be the first ever.’”

China’s early success in containing the pandemic through iron-fist, authoritarian policies emboldened its officials, seemingly giving them license to act with conviction and righteousness.

The tragedies in Xi’an have prompted some Chinese people to question how those enforcing the quarantine rules can behave like this and to ask who holds ultimate responsibility.

“It’s very easy to blame the individuals who committed the banality of evil,” a user called @IWillNotResistIt wrote on Weibo, the Chinese social media platform. “If you and I become the screws in this gigantic machine, we might not be able to resist its powerful pull either.”

Chinese intellectuals are struck by how many officials and civilians — often driven by professional ambition or obedience — are willing to be the enablers of authoritarian policies.

When the coronavirus emerged in Wuhan two years ago, it exposed the weaknesses in China’s authoritarian system. Now, with patients dying of non-Covid diseases, residents going hungry and officials pointing fingers, the lockdown in Xi’an has shown how the country’s political apparatus has ossified, bringing a ruthlessness to its single-minded pursuit of a zero-Covid policy.

The city said 95 percent of its adults were vaccinated by July. In the latest wave, it had reported 2,017 confirmed cases by Monday and no deaths.

Still, it imposed a very harsh lockdown. Residents were not allowed to leave their compounds. Some buildings were locked up. More than 45,000 people were moved to quarantine facilities.

Some residents took to the internet to complain that they didn’t have enough food.

“I only cared about whether I had food to eat,” the young man read, according to a widely shared video. “I didn’t take into account the serious consequences my behavior could bring to the community.” The volunteers later apologized, according to The Beijing News, a state media outlet.

Three men were caught while escaping from Xi’an to the countryside, possibly to avoid the high costs of the lockdown. They hiked, biked and swam in wintry days and nights. Two of them were detained by the police, according to local police and media reports. Together they were called the “Xi’an ironmen” on the Chinese internet.

Then there were the hospitals that denied patients access to medical care and deprived their loved ones the chance to say goodbye.

A deputy director-level official at a government agency in Beijing lost his position last week after some social media users reported that an article he wrote about the lockdown in Xi’an contained untruthful information.

In the article, he called the lockdown measures “inhumane” and “cruel.”

In Xi’an, there is no author like Fang Fang writing her Wuhan lockdown diary, no citizen journalists Chen Qiushi, Fang Bin or Zhang Zhan posting videos. The four of them have either been silenced, detained, disappeared or left dying in jail — sending a strong message to anyone who might dare to speak out about Xi’an.

The Xi’an lockdown debacle hasn’t seemed to convince many people in China to abandon the country’s no-holds-barred approach to pandemic control.

A former athlete who is disabled and suffering from a series of illnesses cursed Fang Fang for her Wuhan diary in 2020. Last month, he posted on his Weibo account that he couldn’t buy medicine because his compound in Xi’an was locked down. His problems were solved, and now he uses the hashtag #everyoneinpositiveenergy and retweets posts that attack Ms. Zhang, the former journalist.

“A needle size loophole can funnel high wind,” he said.

He is the only suspect in the destruction of the historic buildings that housed the National Assembly and the offices of lawmakers, the governing African National Congress and several opposition parties.

On Tuesday, as the judge, Zamekile Mbalo, ordered Mr. Mafe committed to a psychiatric hospital in Cape Town for 30 days, the suspect appeared visibly distressed. He shook his head from side to side, breathing heavily as he clutched his belongings in a shopping bag. His lawyers said he would go on hunger strike to protest his continued detention.

Mr. Mafe’s lawyer, Mr. Mpofu, a former anti-apartheid activist and now a prominent member of an opposition party, has a reputation for taking on politicized cases. He defended a group of veterans accused of briefly holding the defense minister hostage during a meeting over unpaid benefits. Mr. Mpofu is also a lawyer for Jacob Zuma, the former president, appearing on his behalf to appeal his arrest on contempt of court charges last year.

Instead, Mr. Putin is likely not even to have made a decision,

The talks continue on Wednesday, when Russian officials will meet representatives of the United States and its NATO allies in Brussels,

After that, Mr. Peskov said, Russia would decide “whether it makes sense” to move forward with diplomacy.

For years, Mr. Putin has fumed over NATO’s expansion eastward and American support for pro-Western sentiment in Ukraine; now, by creating a new security crisis that threatens to complicate President Biden’s agenda, he has succeeded in getting the issue to the forefront in Washington.

“For the first time in 30 years, the United States has agreed to discuss issues that it was impossible to discuss even a year ago,”

Now that the Russian president has Americans at the negotiating table, he is pursuing another classic Putin strategy: putting so many potential moves on the playing field — pointing in so many different directions — that he leaves people guessing, allowing him to choose the tactics that best suit him as events evolve.

He said Russia was imposing no specific timeline, but that it needed a “fast response” to its demands. And while he said there was “no reason to fear an escalation scenario” in Ukraine

The contradictory messaging continued on Tuesday when the Kremlin’s spokesman, Mr. Peskov, countered any positive assessments Mr. Ryabkov might have offered the day before. “For now, we do not see any substantive reason for optimism,” he said in his daily conference call with reporters.

The virus-free cocoon Mr. Putin has tried to establish around himself has meant that even confidants are forced to spend days in quarantine before being allowed into the same room with him, further reducing his connections with the outside world.

“No one knows with 100 percent certainty whether Putin is ready for war, or whether this is a bluff or not,” Ms. Stanovaya said.

Instead, he has warned of an unspecified “military-technical response” if Russia does not get what it wants.

We need long-term, legally binding guarantees

we need at least something, at least a legally binding agreement rather than just verbal assurances.”

Emboldened, he sees Mr. Biden as a man who may be willing to make a deal — and that Mr. Biden, as a veteran of the Cold War, may possess a respect for power diplomacy with Moscow that younger American politicians do not.

“He assumes that the Americans will pay attention only to that which concretely, immediately threatens them,” Dmitri Trenin, director of the Carnegie Moscow Center think tank, said of the Russian president. “He uses unpredictability, he uses tension, he uses threats.”

it is the demand that NATO offer some kind of formal assurances not to expand eastward and to cease military cooperation with Ukraine that is now most important for Mr. Putin.

NATO has repeatedly ruled out the idea that it would allow any other country to veto who can and cannot be in the alliance, creating what appears to be an impasse.

As for what Russia does next, Mr. Lukyanov said that this would be solely up to Mr. Putin, who exerts a monopoly on foreign-policy decision-making without recent precedent in Russia.

The government has also recently emphasized its dedication to women’s employment rights, especially as it urges women to have more children amid a looming demographic crisis.

Pickup artistry — a practice that arrived in China from the United States — commonly refers to the use of manipulative techniques, including gaslighting, to demean women and lure them into having sex. It became a booming industry in China, with thousands of companies and websites promising to teach techniques, and it has been widely condemned by both the government and social media users.

Women have also been increasingly pushed out of the workplace and into traditional gender roles since China’s leader, Xi Jinping, assumed power. Some fear that the campaign to encourage childbirth could turn coercive.

The gesture, at least, is extensive. As revised, the law would offer the most comprehensive legal definition yet of sexual harassment, to include behaviors such as sending unwanted sexually explicit images or pressuring someone into a relationship in exchange for benefits. It also instructs schools and employers to introduce anti-harassment training and channels for complaints.

The law would also codify women’s right to ask for compensation for housework during divorce proceedings — following the first-of-its-kind decision by a Chinese divorce court last year to award a woman more than $7,700 for her labor during her marriage.

When Peng Shuai, a star tennis player, recently said on social media that a top Chinese leader had pressured her into sex, she was censored within minutes, and many worry that she is under surveillance.

“The priority should be on bottom-up enforcement, where you empower individuals who have been harassed to use the law to protect their rights,” he said.

It is rare for victims of harassment to go to court. An analysis by Mr. Longarino and others found that 93 percent of sexual harassment cases decided in China between 2018 and 2020 were brought not by the alleged victim but by the alleged harasser, claiming defamation or wrongful termination. Women who have made public harassment claims have been forced to pay those they accused.

Nonlegal complaints can bring heavy consequences, too. In December, Alibaba, the e-commerce giant, fired a woman who had accused a superior of raping her. The company said that she had “spread falsehoods,” even though it had earlier fired the man she accused.

Even when women do sue their harassers, they face steep hurdles. Perhaps the most high-profile #MeToo case to go to court was brought by Zhou Xiaoxuan, a former intern at China’s state broadcaster, who asserted that Zhu Jun, a star anchor, had forcibly kissed and groped her. But the case faced years of delays. In September, a court dismissed the claim and said she had not provided enough evidence, though Ms. Zhou said the judges had rejected her efforts to introduce more.

several male bloggers with large followings on the social media platform Weibo denounced the provisions against degrading or harassing women online, saying they would give “radical” feminists too much power to silence their critics.

A woman in southern Guangdong Province who asked to use only her last name, Han, out of fears for her safety, said that she had endured years of physical and emotional abuse by her ex-husband. Even though she managed to secure a divorce last year, he continues to stalk and threaten her, she said. She obtained a restraining order, viewed by The New York Times, that cited chat logs and recordings.

If the law is revised, she continued, the police will be forced to recognize that she has a right to seek their help.

His voice was a powerful force for nonviolence in the anti-apartheid movement, earning him a Nobel Peace Prize in 1984.

“You are overwhelmed by the extent of evil,” he said. But, he added, it was necessary to open the wound to cleanse it. In return for an honest accounting of past crimes, the committee offered amnesty, establishing what Archbishop Tutu called the principle of restorative — rather than retributive — justice.

Archbishop Tutu preached that the policy of apartheid was as dehumanizing to the oppressors as it was to the oppressed. At home, he stood against looming violence and sought to bridge the chasm between Black and white; abroad, he urged economic sanctions against the South African government to force a change of policy.

But as much as he had inveighed against the apartheid-era leadership, he displayed equal disapproval of leading figures in the dominant African National Congress, which came to power under Nelson Mandela in the first fully democratic elections in 1994.

“many, too many, of our people live in grueling, demeaning, dehumanizing poverty.”

“We are sitting on a powder keg,” he said.

The cause of death was cancer, the Desmond and Leah Tutu Legacy Foundation said, adding that Archbishop Tutu had died in a care facility.

“I think we are at a bad place in South Africa,” Archbishop Tutu told The New York Times Magazine in 2010, “and especially when you contrast it with the Mandela era. Many of the things that we dreamed were possible seem to be getting more and more out of reach. We have the most unequal society in the world.”

This government, our government, is worse than the apartheid government,” he said, “because at least you were expecting it with the apartheid government.”

In elections in 2016, while still under the leadership of Mr. Zuma, the party’s share of the vote slipped to its lowest level since the end of apartheid. Mr. Ramaphosa struggled to reverse that trend, but earned some praise later for his robust handling of the coronavirus crisis.

Politics were inherent in his religious teachings. “We had the land, and they had the Bible,” he said in one of his parables. “Then they said, ‘Let us pray,’ and we closed our eyes. When we opened them again, they had the land and we had the Bible. Maybe we got the better end of the deal.”

Although Archbishop Tutu, like other Black South Africans of his era, had suffered through the horrors and indignities of apartheid, he did not allow himself to hate his enemies.

He coined the phrase “rainbow nation” to describe the new South Africa emerging into democracy, and called for vigorous debate among all races.

Archbishop Tutu had always said that he was a priest, not a politician, and that when the real leaders of the movement against apartheid returned from jail or exile he would serve as its chaplain.

While he never forgot his father’s shame when a white policeman called him “boy” in front of his son, he was even more deeply affected when a white man in a priest’s robe tipped his hat to his mother, he said.

But Archbishop Tutu did not stay entirely out of the nation’s business.

When Desmond was hospitalized with tuberculosis, Father Huddleston visited him almost every day. “This little boy very well could have died,” Father Huddleston told an interviewer many years later, “but he didn’t give up, and he never lost his glorious sense of humor.”

After his recovery, Desmond wanted to become a doctor, but his family could not afford the school fees. Instead he became a teacher, studying at the Pretoria Bantu Normal College and earning a bachelor’s degree from the University of South Africa. He taught high school for three years but resigned to protest the Bantu Education Act, which lowered education standards for Black students.

By then he was married to Nomalizo Leah Shenxane, a major influence in his life

He was named Anglican dean of Johannesburg in 1975 and consecrated bishop of Lesotho the next year. In 1978 he became the first Black general secretary of the South African Council of Churches, and began to establish the organization as a major force in the movement against apartheid.

Under Bishop Tutu’s leadership, the council established scholarships for Black youths and organized self-help programs in Black townships. There were also more controversial programs: Lawyers were hired to represent Black defendants on trial under the security laws, and support was provided for the families of those detained without trial.

A month after he was awarded the Nobel Peace Prize in 1984, Desmond Tutu became the first Anglican bishop of Johannesburg when the national church hierarchy intervened to break a deadlock between Black and white electors. He was named archbishop of Cape Town in 1986, becoming spiritual head of the country’s 1.5 million Anglicans, 80 percent of whom were Black.

“I am a man of peace, but not a pacifist.”

In 2021, as he approached his 90th birthday, he pitched into a fraught debate as disinformation about coronavirus vaccines swirled.

He remained equally outspoken even in later years. In 2003 he criticized his own government for backing Zimbabwe’s president, Robert Mugabe, who had a long record of human rights abuses.

On his frequent trips abroad during the apartheid era, Archbishop Tutu never stopped pressing the case for sanctions against South Africa. The government struck back and twice revoked his passport, forcing him to travel with a document that described his citizenship as “undetermined.”

Still, when the Truth and Reconciliation Commission issued its final findings in 2003, Archbishop Tutu’s imprint was plain. It warned the government against issuing a blanket amnesty to perpetrators of the crimes of apartheid and urged businesses to join with the government in delivering reparations to the millions of Black people victimized by the former white minority government.

Archbishop Tutu officially retired from public duties in 2010. One of his last major appearances came that year, when South Africa hosted the World Cup

But he did not retreat from the public eye entirely. In June 2011, he joined Michelle Obama at the new Cape Town Stadium, built for the tournament, where she was promoting physical fitness during a tour of southern Africa.

In an interview in the early 1980s, he said: “Blacks don’t believe that they are introducing violence into the situation. They believe that the situation is already violent.”

“There is nothing to fear,” he said. “Don’t let Covid-19 continue to ravage our country, or our world. Vaccinate.”

She has served four years and nine months of her sentence so far. Concerns about her health were raised after she was taken to a hospital in Seoul, the capital, for various illnesses last month.

Mr. Moon said that Ms. Park’s declining heath had also been a factor in his government’s decision to release her.

Ms. Park was pardoned under a broad amnesty that benefited 700 other prisoners, whose remaining prison terms will be eradicated or cut in half. The South Korean president has the power to grant amnesty to prisoners under the Constitution, and has often exercised it to mark major national holidays or the beginning of a new year.

Ms. Park, a daughter of the former military dictator Park Chung-hee, was in her fourth year in power in 2016 when hundreds of thousands of protesters began months of weekly rallies in central Seoul demanding that she be forced from office for corruption and incompetence.

In January this year, the Supreme Court approved a reduced 20-year prison term for Ms. Park and ordered her to pay 18 billion won ($15 million) in fines, saying that she and her longtime friend and confidante Choi Soon-sil had collected or demanded $19.3 million in bribes from three big businesses, including $7 million from Samsung, South Korea’s largest and most lucrative business group.

The younger Mr. Lee, who was sentenced to two and a half years in prison in the corruption scandal, was released on parole in August, when South Korea freed hundreds of prisoners to mark the Aug. 15 National Liberation Day, which commemorates the end of Japanese colonial rule of South Korea at the end of World War II.

Despite her conviction, Ms. Park still had a sizable following of die-hard supporters, mostly older conservative South Koreans, who have held rallies in downtown Seoul calling her innocent and demanding her release.

Those who have argued for her pardon have compared her case to those of the former military dictators Chun Doo-hwan and Roh Tae-woo.

Mr. Moon’s government granted a special amnesty to former Prime Minister Han Myeong-sook, one of the president’s former political allies. Ms. Han was sentenced to two years in prison in 2015 on charges of collecting illegal political donations. She finished her term in 2017.

The government also released Lee Seok-ki, a progressive politician, on parole on Friday. He was arrested by Ms. Park’s government in 2013 on charges of conspiring to start an armed revolt to overthrow the Seoul government in the event of war with North Korea. He has served all but nine months of his nine-year sentence.

calling him a victim of what they saw as a political witch hunt by Ms. Park to repress her political enemies.

Ms. Herrera said she had no additional information about the decision, though she noted that petitions were pending before the Supreme Court to commute the women’s sentences.

The three are among at least 17 Salvadoran women activists consider unjustly convicted and imprisoned following obstetric emergencies and who have been at the center of a campaign against El Salvador’s absolute law against abortions.

“We are grateful that our petitions are being heard and we trust that President Bukele is going to work to achieve freedom for the rest of the innocent women,” said Paula Avila-Guillén, executive director of the Washington-based Women’s Equality Center.

El Salvador is among four countries in Latin America that ban abortion in all cases, including when the life of the mother is at risk and in cases of rape. The others are Nicaragua, Honduras and the Dominican Republic. Charges of homicide are often brought in abortion cases.

In December of last year, Argentina legalized abortion, and in September of this year, Mexico’s Supreme Court decriminalized abortion.

Most of the advisory panel argued that the potential benefits of a fourth dose outweighed any risks,

Also Monday, the Israeli Health Ministry formally accepted another of the recommendations of the advisory board, shortening the period between administering a third booster shot after the second vaccine to three months from five months

Most of Israel’s population has received at least two doses, but about a million eligible citizens have not yet received a third booster shot, out of a total population of nine million.

Islington’s project is just one of many innovations by cities around the world to provide heat to residents and businesses while reducing greenhouse gas emissions, improving efficiency and saving people money.

Stockholm is also using heat from sewage, as well as tapping data centers and other sources to supply heat for much of the city.

If you can start to use a whole array of waste heat streams, you’re taking out a big chunk of greenhouse gas emissions,

We don’t really need to burn gas at 1,000 degrees centigrade [1,832 degrees Fahrenheit] to get your bath to 30 degrees centigrade,” Dr. Gluyas added. “What we need to do is work with nature to optimize the use of heat.

The concept of district heating networks is not new and may, in fact, date from 14th-century France or even, some say, the Roman Empire

New York City has one of the world’s largest district systems to provide heat, cooling and, in some cases, even electricity to many buildings in Manhattan.

Stockholm, Mr. Rylander said, has particularly good connectivity to Northern Europe, Finland and Russia, which makes it attractive to data center companies, as does Sweden’s relatively clean power mix. However, they use biomass to produce a significant amount of heat and power, the renewable classification of which is debated by experts.

But the innovation — which took more than five years to plan and build, and began operations in March 2020 — was to feed in heat from the Underground.

Typically, the hot air from the Underground is released into the air through stations and ventilation shafts. In this case, however, air is drawn from a ventilation shaft at an abandoned Underground station into an energy center where a series of heat transfers take place, eventually leading to delivery of the heat into the buildings in the network.

For our residents, locally, this is absolutely the right thing to do,” because it saves money in an area where many residents struggle to afford heat, Mr. Townsend said. “And this is a perfect solution for big cities across the world.

Heat from wastewater and sewage now provides about 70 percent of the space heating and hot water for the 43 buildings connected to the network, with the remaining 30 percent coming from natural gas, though the goal is to end that by 2030. The electricity powering the heat pumps is 97 percent zero-carbon, supplied by hydroelectric dams.

Every time we take a shower, do the dishes or do a load of laundry, the water is still hot when it goes down the drain,” said Ashley St. Clair, Vancouver’s senior renewable energy planner.“It’s flowing under our streets, and we’re already collecting it through the traditional infrastructure of wastewater pipes, and to be able to tap into that waste heat is really the ultimate circular economy.”

And it cannot come soon enough: This year alone, Vancouver has experienced several bouts of extreme weather, made more likely and intense because of climate change: heat domes, wildfires and catastrophic flooding, which recently cut the city off by road and rail from the rest of Canada. Having its own heat and hot water supply has been an additional benefit of the project, Ms. St. Clair said.

Though perhaps less wasteful than having a boiler in every single building, it is not the most efficient district heating system, as it was designed to heat a building on the coldest day of the year with all the windows open — partly a public health legacy of the 1918 pandemic.

“If you establish a data center in a cold place like Sweden, it’s stupid to waste the heat, because heat has power and value in a cold country.”

“We’re very clear that we are an experiment, and we are doing the work that will enable others to benefit from it.”

“Don’t, don’t, don’t, don’t,” Mr. Trump said, waving his arm to dismiss the naysayers and downplaying the size of the reaction by pointing to what he said was “a very tiny group over there.”

micron is now the dominant version of new coronavirus cases in the United States, according to the Centers for Disease Control and Prevention.

Vaccinated people without booster shots are believed to be more vulnerable to infection by Omicron, and government officials nationwide say boosters are the best response to the new variant.

Just before the booing, Mr. Trump said that his supporters should get vaccinated because, he suggested, unwillingness to do so represented a victory for liberals. “What we’ve done is historic,” he said of the three Covid vaccines in use in the United States that were developed while he was in office. “Don’t let them take away, don’t take it away from ourselves. You’re playing right into their hands when you sort of like, ‘oh, the vaccine.’”

You shouldn’t be forced to take it, no mandates. But take credi

The Senate deal, which was reached late Friday night, was a grudging concession by Democrats to Republican Senator Ted Cruz of Texas, who has delayed the confirmation of dozens of President Biden’s nominees to protest what he called Mr. Biden’s weak opposition to the pipeline.

Mr. Cruz and others insist that Nord Stream 2 will provide Russia with a cash infusion and dangerous control over Europe’s energy supplies, while potentially costing Ukraine’s government around $3 billion in annual transit fees from a similar pipeline through its territory that Russia could circumvent.

“When the Senate reconvenes, we’ll finally have a vote on sanctioning Putin’s pipeline.”

The $11 billion pipeline was completed in September but is awaiting certification to become operational.

Biden officials said at the time that while they opposed construction of the pipeline, which will pump gas from the Russian Arctic to Germany through the Baltic Sea, the project was nearly complete by the time Mr. Biden took office and virtually impossible to stop. At this point, White House officials say, the cost of friction with the German government outweighs any potential loss to Mr. Putin.

some analysts say the pipeline may be less important to Mr. Putin than his longtime designs on Ukrainian territory.

A Dec. 7 call between Mr. Biden and Mr. Putin has done little to soothe the situation, and last week the Kremlin issued a set of demands that Biden officials called largely unacceptable.

Senator Chris Coons, Democrat of Delaware and a close Biden ally who helped to negotiate the deal, said he would wait to see the final language in the measure and confer with Biden officials before deciding how he will vote. A State Department spokesman did not respond to a request for comment.AdvertisementContinue reading the main storyMr. Coons said he recently met in Berlin with Olaf Sholz, who succeeded Angela Merkel this month as Germany’s chancellor. He noted the new German government’s pledge not to certify the pipeline until well into 2022.

“Imposing sanctions on a close ally like Germany when they are moving in the right direction is something that I would not do lightly,” Mr. Coons said.

“We need a fully staffed senior team at the State Department and at the United Nations, and ambassadors around the world,” Mr. Coons said. “And while I respect that senators of both parties have the right to use the occasional hold to force a policy discussion, I think this has gotten way out of hand.”

Noting that other countries had taken steps to restrict access to the site, the lawmakers also asked about removing it from search results in the United States.

Members of the site are anonymous, but The Times identified 45 people who had spent time on the site and then killed themselves in the United States, the United Kingdom, Italy, Canada and Australia. Most of them were under 30, including several teenagers. The Times also found that more than 500 members of the site wrote so-called goodbye threads announcing how and when they planned to end their lives, and then never posted again.

And the new administrator made the site private, meaning that the content — including discussions about suicide methods, messages of support and thumbs-up emojis to those sharing plans to take their lives, and even real-time posts written by members narrating their attempts — is now visible only to members and not the public.

The site draws six million page views a month, and nearly half of all traffic is driven by online searches, according to data from Similarweb, a web analytics company.

Citing The Times’s reporting, Mr. Blumenthal wrote in his letter, addressed to Google’s chief executive, Sundar Pichai, that the content on the suicide site “makes the world a dark place for too many,” and that Google had the ability and legal authority to steer “people who are struggling away from this dangerous website.”

Google’s hands are not tied, and it has a responsibility to act,

The operators of the suicide site have long used Cloudflare, an American firm that provides cyberprotections, to obscure the names of its web host, making it difficult or impossible to know what company is providing those services.

After the article was published, on Dec. 9, Marquis announced on the site that he was resigning as an administrator, permanently deleting his account and turning over operation of the site to someone using the online name RainAndSadness.

In Uruguay, where assisting suicide is a crime, the Montevideo police have begun an inquiry in collaboration with a local prosecutor’s office in response to The Times’s investigation, said Javier Benech, a communications director for the office.

In the United States, while many states have laws against assisting suicide, they are often vague, do not explicitly address online activity and are rarely enforced.

Members of the suicide site who post instructions on how to die by suicide, or encouragement to follow through with it, could be vulnerable to criminal charges depending on the jurisdiction. But so far, no American law enforcement officials have pursued such cases in connection with the website. Federal law typically protects website operators from liability for users’ posts.

this month that about 400 investigations had been opened into networks of people suspected of providing the fake passes, including some connected to health professionals.

a nurse injecting vaccine doses into a gauze pad and then pretending to inject the contents of empty syringes into people’s arms.

Eight other people are thought to have been falsely vaccinated at the Palermo hub, according to Francesco Lo Voi, the local prosecutor. He said an initial investigation suggested that other health workers at the center had been unaware of the fraud.
