In interviews with senior American and European officials in recent days, there is a consensus on one point: Just as the last two weeks revealed that Russia’s vaunted military faltered in its invasion plan, the next two or three may reveal whether Ukraine can survive as a state, and negotiate an end to the war.

And there is the possibility that Mr. Putin, angered by the slowness of his offensive in Ukraine, may reach for other weapons: chemical, biological, nuclear and cyber.

Mr. Sullivan said that Russia would suffer “severe consequences” if it used chemical weapons, without specifying what those would be.

Quietly, the White House and the senior American military leadership have been modeling how they would respond to a series of escalations, including major cyberattacks on American financial institutions and the use of a tactical or “battlefield” nuclear weapon by Mr. Putin to signal to the rest of the world that he would brook no interference as he moves to crush Ukraine.

Even with Ukrainians begging for more offensive weapons and American intervention, Mr. Biden has stuck to his determination that he will not directly engage the forces of a nuclear-armed superpower.

The idea that we’re going to send in offensive equipment,” Mr. Biden said in Philadelphia to the House Democratic Caucus on Friday, “and have planes and tanks and trains going in with American pilots and American crews, just understand — and don’t kid yourself, no matter what you all say — that’s called ‘World War III.’ OK? Let’s get it straight here.”

A French government account of a call to Mr. Putin on Saturday by Mr. Macron and Mr. Scholz termed it “disappointing with Putin’s insincerity: He is determined to continue the war.”

no evidence from the conversations so far that Mr. Putin has changed course; he remains “intent on destroying Ukraine.”

Despite his military’s logistical problems, Mr. Putin appears intent on intensifying his campaign and laying siege to Kyiv, the capital; Kharkiv, the country’s second-largest city; and other Ukrainian urban centers.

“I think Putin is angry and frustrated right now,” Mr. Burns said. He is likely to “try to grind down the Ukrainian military with no regard for civilian casualties,” he added.

Mr. Putin has demonstrated in past conflicts in Syria and Chechnya a willingness not only to bomb heavily populated areas but also to use civilian casualties as leverage against his enemies. Senior U.S. officials said the coming weeks could see a long, drawn-out fight with thousands of casualties on both sides, as well as among the roughly 1.5 million citizens remaining in the city.

“It will come at a very high price in Russian blood,” said retired Adm. James G. Stavridis, the former supreme allied commander for Europe. That high cost, he added, could cause Mr. Putin to destroy the city with an onslaught of missiles, artillery and bombs — “continuing a swath of war crimes unlike any we have seen in the 21st century.”

Russian forces are still subjecting Mariupol to siege and bombardment, but are close to securing that strategic southern port city and, with it, a land bridge from Crimea in the south to the Donbas region in the east that has been controlled by Russian-backed separatists since 2014.

And if Russia can seize Odessa, a pivotal Black Sea port city, and perhaps the remaining Ukrainian coast to the southeast, it would deprive Ukraine of important access to the sea.

“The most probable endgame, sadly, is a partition of Ukraine,” said Mr. Stavridis, pointing to the outcome of the Balkan wars in the 1990s as a model. “Putin would take the southeast of the country, and the ethnic Russians would gravitate there. The rest of the nation, overwhelmingly Ukrainian, would continue as a sovereign state.”

The fear now is that the war could expand.The more the fighting moves west, the more likely it is that an errant missile lands in NATO territory, or the Russians take down a NATO aircraft.

So far there are none of the procedures in place that American and Russian pilots use over Syria, for example, to prevent accidental conflict. And Mr. Putin has twice issued thinly veiled reminders of his nuclear capabilities, reminding the world that if the conflict does not go his way he has far larger, and far more fearsome, weapons to call into play.

Ms. Thomas has previously pushed back against an ongoing congressional investigation into what took place that day. In December, she co-signed a letter calling for House Republicans to expel Representatives Liz Cheney of Wyoming and Adam Kinzinger of Illinois from their conference for joining the congressional committee investigating the attacks.

Ms. Thomas did not answer detailed questions from The Times about its findings. Her comments to The Free Beacon were her first about her participation in the rally. She said she had attended the rally in the morning but left before President Donald J. Trump addressed the crowd.

“As a member of their 501(c)(4) board, candidly, I must admit that I do not attend many of those separate meetings, nor do I attend many of their phone calls they have,” she said. “At CNP, I have moderated a session here and there. I delivered some remarks there once too.”

Dustin Stockton, one of the organizers involved in the Jan. 6 rally, told The Times that Ms. Thomas had played a peacemaking role between feuding factions of rally organizers “so that there wouldn’t be any division.” Ms. Thomas disputed that, saying there were “stories saying I mediated feuding factions of leaders for that day. I did not.”

She also said she “played no role with those who were planning and leading the Jan. 6 events.”

But after the number changes to 988 — a shift that involves upgrading telecom infrastructure and bringing more call centers online — use of the hotline is expected to grow exponentially over the next few years. (The current number is 800-273-8255.)

The only call center in South Carolina, for instance, until recently operated out of an old, dark basement, near a boiler room. The last remaining one in Louisiana has struggled to keep up with an influx of calls after another center closed and its replacement went offline during the pandemic. Minnesota and Wyoming have had periods with no centers at all. When local centers cannot pick up, calls are pushed to national backup centers, where counselors are less likely to be familiar with local resources and wait times can be too long for people in crisis.

As a teenager, she made dozens of late-night calls to the Lifeline. A volunteer named Chris, who worked the late shift, usually would pick up and talk her to safety. But during the last several years, she has found it increasingly difficult to reach a counselor. Several times, she said, she hung up and harmed herself.

A woman from Michigan, who said she waited twice for over an hour before hanging up, likened the experiences to calling airline customer service — except that she was seeking suggestions on “not killing myself.” A teenager from Mississippi recounted calling three times one night without getting through, and then overdosing.

For 988, such fees could also help pay for mobile response teams that can be dispatched to people in crisis, as well as for specialized triage centers — both significant, and costly, elements of what advocates see as a watershed opportunity to recast the delivery of mental health care.

“Our concern is very much about whether there will be someone to answer that call when someone is in crisis,” said Hannah Wesolowski, chief advocacy officer for the National Alliance on Mental Illness.

“There are thousands of users — many of whom may be in suicidal crisis — who seek assistance and are unable to get the lifesaving help they deserve,” the report said.

Paying for 988, and what comes with it, has emerged as a contentious issue for states. Some lawmakers are wary of adding what they see as a new tax. Others think 988 is redundant with other resources. And telecommunications lobbyists, while broadly supportive of 988, have pushed back on some proposed fees.

“It is just like the United States Congress, though, to send us something like this” — with instructions that “you are going to fund it,” he said.

“With all due respect, 988 is going to save the taxpayers a whole lot of money,” he said.

“The crisis centers are like, ‘You don’t get any of those other things if people aren’t here to answer the phone,’” said Ms. Battle, director of access at the Harris Center, which provides services for mental health issues and developmental disabilities.

One goal of 988 is to eventually answer 95 percent of all incoming calls within 20 seconds. The data analysis showed that only two states had Lifeline answer rates above 95 percent in the fourth quarter of last year. Thirty-three states had more than 15 percent of their calls abandoned.

“People call in their most dire state of need.”

West Virginia’s lone call center answering the Lifeline, First Choice Services, also answers more than 15 other numbers, including ones for gambling, tobacco and drug and alcohol addiction, most with volume rising during the pandemic.

“We have a very real fear that without funding our program in a substantial way,” she said, “our West Virginia callers will suddenly be facing what has been a problem nationally.”

“We were the first human eyes to be looking at this since that dramatic moment. I about jumped out of my chair.”

In 2021, the Great Lakes Shipwreck Historical Society, the nonprofit that operates the museum, had its best season for locating wrecks, Mr. Lynn said, helped by good weather and side-scan sonar, which sends and receives acoustic pulses that help map the seafloor and detect submerged objects. It discovered nine shipwrecks, including the Atlanta, the most in any season, after towing the sonar 2,500 miles, said Darryl Ertel, the society’s director of marine operations.

“It was a target we had found earlier but were not exactly sure what it was,” Mr. Lynn said. “You never quite know until you see a smoking gun. That name board was it. It announced with no uncertain terms, ‘This is what I am.’”

The Atlanta’s voyage was typical of the Industrial Revolution, when schooner barges hauled iron ore and coal across Lake Superior, said Fred Stonehouse, a local historian.

“This is really about solving historical mysteries,” Mr. Stonehouse said.

The Atlanta will remain undisturbed. A Michigan law makes it illegal to raise shipwrecks, but Mr. Lynn said it would also be like raiding a burial plot.

“These are like grave sites,” he said. Finding the Atlanta, he added, “was fortunate. There were survivors who can tell us what happened.”

On Friday, the justices of the Texas Supreme Court, all Republicans, said that those officials did not, in fact, have any power to enforce the law, “either directly or indirectly,” and so could not be sued.

“This measure, which has saved thousands of unborn babies, remains fully in effect, and the pro-abortion plaintiffs’ lawsuit against the state is essentially finished,” he wrote on Twitter.

The law allows no exceptions for abortion even in the case of women who have been raped or are victims of incest. It has thrown Texas abortion providers into crisis, and similar legislation is pending around the country.

“If conservative states want to do things that may not look constitutional even to this Supreme Court, they can use a bounty system to achieve that,” Professor Ziegler said. “The message sent by the Texas litigation was that if you have concerns that you might lose a constitutional challenge, that shouldn’t hold you back. Because you can use this road map to keep the case out of federal court entirely.”

“We’ve known that this lawsuit all along was just invalid and should have been dismissed, and now the fact that we’re on that trajectory now is encouraging,” Ms. Schwartz said, adding that the movement “is not going to let our foot off the gas yet.”

Amy Hagstrom Miller, the chief executive of Whole Woman’s Health, the clinic that sued to stop S.B. 8, said “the courts have failed us.”

“This ban does not change the need for abortion in Texas, it just blocks people from accessing the care they need,” she said. “The situation is becoming increasingly dire,”

Many women have traveled to Oklahoma for the procedure, but this week the State Senate passed its own six-week ban modeled on the Texas law. The Idaho Senate passed a similar law last week. Lawmakers in other states have proposed similar bans, but have held off in hopes that the Supreme Court decision, expected in June, will allow them to ban abortion entirely.

“This means that as long as we don’t commit terminal strategic blunders, China’s modernization will not be cut short, and on the contrary, China will have even greater ability and will to play a more important role in building a new international order,” Zheng Yongnian, a professor at the Chinese University of Hong Kong, Shenzhen, who has advised senior officials, wrote after the invasion in a widely circulated article.

At the heart of China’s strategy lies a conviction that the United States is weakened from reckless foreign adventures, including, from Beijing’s perspective, goading Mr. Putin into the Ukraine conflict.

China’s path ahead is by no means certain. Drawing too close to Russia would risk entrenching animosity toward China in Europe and beyond, a possibility that worries Mr. Xi’s government, for all its bluster.

The United States’ allies in the Pacific, including Japan and Australia, “will also adopt a stronger military posture. So it all seems unfriendly to China.”

It’s not just China’s reputation in the West; I think it also affects China’s reputation in the non-West, because it’s essentially associating itself with an imperial power.”

In any case, China’s economy is large enough to absorb blows that would cripple others. Chinese companies may even end up well positioned to take advantage of Russia’s desperate need for trade, as happened when Moscow faced sanctions over the annexation of Crimea in 2014.

“Biden has repeatedly avowed that the United States is not in a ‘new Cold War’ with China, but China often feels the chill creeping in everywhere.”

Just as Mr. Putin depicts the United States as menacing Russia on its western frontier, Mr. Xi sees American support for Taiwan, the self-governing island democracy that Beijing claims as its own, as a similar threat off China’s coast.

“The West should not have become a hegemon in defining universal standards because the West or Europe, or the West in general is only part of humanity,” Mr. Dugin told a Chinese state television interviewer in 2019. “And the other part, a majority of human beings, live outside the West, in Asia.”

As it turns to Beijing for support against Western sanctions, Russia will become increasingly beholden to China as its diplomatic and economic lifeline, while serving as its strategic geopolitical ballast, analysts say.

The violence in the Benishangul-Gumuz region, which is home to several ethnic groups, is separate from the war in the northern Tigray region that erupted in November 2020 between Ethiopian federal forces and rebellious forces of the Tigray People's Liberation Front (TPLF).

A total of 47 people, including prominent Shiite Muslim cleric Nimr al-Nimr, were executed in one day in 2016.

Saudi Arabia denies accusations of human rights abuses and says it protects its national security according to its laws.

But some research has concluded that deforestation, drying and other factors could lead to substantial forest dieback in the Amazon by the end of this century.

Covering more than two million square miles in Brazil and neighboring countries, the Amazon is the world’s largest rainforest, and serves a crucial role in mitigating climate change in most years by taking in more carbon dioxide from the atmosphere than it releases.

“That lack of resilience shows that, indeed, there is only so much of a beating that this forest can take,”

But climate change, together with widespread deforestation and burning for agriculture and ranching, has taken a toll on the Amazon, making it warmer and drier. The region, one of the wettest on Earth, has experienced three droughts since 2000.

“It’s reducing the ability to bounce back.”

The researchers found that more than three-quarters of the untouched rainforest lost resiliency over that time, and that the loss was greatest in areas that were drier or closer to human activities like logging. The study was published in the journal Nature Climate Change.

About 17 percent of the Amazon has been deforested over the past half-century, and while the pace of deforestation slowed for some years in Brazil, it has picked up again more recently

The implications for China extend beyond Ukraine, and even Europe.

“He’s damned if he did know, and damned if he didn’t,” Paul Haenle, a former director for China on the National Security Council, said of whether Mr. Xi had been aware of Russia’s plans to invade. “If he did know and he didn’t tell people, he’s complicit; if he wasn’t told by Putin, it’s an affront.”

In any case, the invasion evidently surprised many in Beijing’s establishment

Mr. Xi’s statement with Mr. Putin on Feb. 4 endorsed a Russian security proposal that would exclude Ukraine from joining the North Atlantic Treaty Organization.

Even so, as Mr. Putin became determined to reverse Ukraine’s turn to Western security protections, Chinese officials began to echo Russian arguments. Beijing also saw a growing threat from American-led military blocs.

“Putin may have done this anyway, but also it was unquestionably an enabling backdrop that was provided by the joint statement, the visit and Xi’s association with all of these things,”

“He owns that relationship with Putin,” Mr. Haenle said. “If you’re suggesting in the Chinese system right now that it was not smart to get that close to Russia, you’re in effect criticizing the leader.”

For decades it sought to build ties with Russia while also keeping Ukraine close.

Over the past years, as growing numbers of Ukrainians supported joining NATO, Chinese diplomats did not raise objections with Kyiv, said Sergiy Gerasymchuk, an analyst with Ukrainian Prism, a foreign policy research organization in Kyiv.

For both leaders, their partnership was an answer to Mr. Biden’s effort to forge an “alliance of democracies.”

Before and shortly after the invasion, Beijing sounded sympathetic to Moscow’s security demands, mocking Western warnings of war and accusing the United States of goading Russia. Over the past two weeks, though, China has sought to edge slightly away from Russia. It has softened its tone, expressing grief over civilian casualties. It has cast itself as an impartial party, calling for peace talks and for the war to stop as soon as possible.

Beijing had its own complaints with NATO, rooted in the bombing of the Chinese Embassy in Belgrade, Serbia, during NATO’s war in 1999 to protect a breakaway region, Kosovo. Those suspicions deepened when NATO in 2021 began to describe China as an emerging challenge to the alliance.

n Feb. 23, a foreign ministry spokeswoman, Hua Chunying, accused Washington of “manufacturing panic.”

Chinese officials tweaked their calls to heed Russia’s security, stressing that “any country’s legitimate security concerns should be respected.” They still did not use the word “invasion,” but have acknowledged a “conflict between Ukraine and Russia.”

“Many decision makers in China began to perceive relations in black and white: either you are a Chinese ally or an American one,”

“They still want to remain sort of neutral, but they bitterly failed.”

The attack on Friday broke a relative lull in violence in Peshawar, which has borne the brunt of Taliban militancy in recent years. Sheikh Rashid Ahmed, the interior minister, called the attack an attempt to “disrupt peace and tranquillity of the provincial capital,” according to state-run news media.

In May 2019, ISIS-K created a separate Pakistani chapter, which has carried out attacks in Baluchistan Province, targeting ethnic Hazara Shiites.

Last fall, ISIS-K carried out high-profile bombings at two Shiite mosques in Afghanistan, killing and wounding dozens.

A second mosque attack on Friday, in Paktia Province in Afghanistan, southwest of Peshawar, killed at least three people and wounded more than two dozen after an explosive device was detonated, according to a Taliban spokesman.

North Korea conducted seven missile tests in January, more than in all of 2021. ​It refrained from weapons tests ​for most of February, possibly out of deference to China, its neighbor and only major ally, which was hosting the Winter Olympics in Beijing.

​The resumption of North Korean weapon tests comes as the Biden administration is focused on the crisis in Ukraine, and as South Korea is in the midst of a presidential campaign. South Korea goes to the polls on Wednesday to elect the replacement for President Moon Jae-in, whose single five-year term ends in May.

North Korea has often been accused of attempting military provocations to influence elections in the South. Prof. Lee recalled that in December 2012, just a week before the South Korean presidential election, North Korea launched a rocket under the pretext of putting a satellite into orbit.

Since the North does not want a hawkish right-wing leader to take power in the South, it will refrain from attempting a major military provocation before the election, said Cheong Seong-chang, director of the Center for North Korean Studies at the Sejong Institute in South Korea.

But once the election is over, it will likely step up weapons tests to celebrate the 110th birthday of Kim Il-sung, the North Korean founder and grandfather of the current leader, Kim Jong-un, Mr. Cheong said. The senior Kim’s birthday is April 15.

Women planning to join the Aurat Marches, as they are called — Urdu for “women’s march” — have faced countless threats of murder and rape, along with accusations that they receive Western funding as part of a plot to promote obscenity in Pakistan.

Last year, opposition peaked when Islamist groups demonstrated in major cities, accusing the marchers of using blasphemous slogans — a crime punishable by death in Pakistan, accusations of which have provoked lynchings and murders.

The first Aurat March was organized by a small group of women in the port city of Karachi, who hoped to draw attention to the violence, inequality and other challenges faced by women across the country.

“We had held discussions and mobilized women in various communities, collected funds by small contributions from individuals, and wrote a manifesto to articulate demands related to women’s bodily rights to the government and Pakistani society,” Ms. Kermani said.

“Younger feminists who were inspired by a series of global women’s marches took their rage against violence, moral policing and lack of bodily or sexual choices for women and marginalized genders to the streets,” s

powerful figures in Pakistan want the event banned altogether.

the protesters had even highlighted L.G.B.T.Q. rights, a bold move in Pakistan.

Some Islamist parties responded to the marches’ growing popularity by organizing their own “modesty march.” In 2020, conservatives filed court petitions in an unsuccessful attempt to stop the Aurat Marches.

A newspaper published a front-page story that referred to the marchers as prostitutes.

“If the government allows the march, we will use a baton to stop it.”

“Save our daughters.”

“As a minority, we feel increasingly insecure,” Mrs. Masih said. “At the workplace, we fear anyone can harm us on the false allegations of blasphemy, and at our homes, we fear that our daughters could be kidnapped and converted to Islam

They campaigned against the physically intrusive “virginity tests” often inflicted on women who bring accusations of rape, and a court in the northern city of Lahore banned them last year. The government has also passed a measure allowing the chemical castration of convicted rapists, another demand of the marchers.

“We were and are scared, but we know that without putting ourselves in such a dangerous situation we cannot bring change,” Ms. Kermani said.

Many popular TikTok videos of the invasion — including of Ukrainians livestreaming from their bunkers — offer real accounts of the action, according to researchers who study the platform. But other videos have been impossible to authenticate and substantiate. Some simply appear to be exploiting the interest in the invasion for views, the researchers said.

The clip was then used in many TikTok videos, some of which included a note stating that all 13 soldiers had died. Ukrainian officials later said in a Facebook post that the men were alive and had been taken prisoner, but the TikTok videos have not been corrected.

“People trust it. The result is that a lot of people are seeing false information about Ukraine and believing it.”

TikTok and other social media platforms are also under pressure from U.S. lawmakers and Ukrainian officials to curb Russian misinformation about the war, especially from state-backed media outlets such as Russia Today and Sputnik.

For years, TikTok largely escaped sustained scrutiny about its content. Unlike Facebook, which has been around since 2004, and YouTube, which was founded in 2005, TikTok only became widely used in the past five years.

The app has navigated some controversies in the past. It has faced questions over harmful fads that appeared to originate on its platform, as well as whether it allows underage users and adequately protects their privacy.

That includes TikTok’s algorithm for its “For You” page, which suggests videos based on what people have previously seen, liked or shared. Viewing one video with misinformation likely leads to more videos with misinformation being shown, Ms. Richards said.

But audio can be misused and taken out of context, Ms. Richards said.

“Video is the hardest format to moderate for all platforms,” said Alex Stamos, the director of the Stanford Internet Observatory and a former head of security at Facebook. “When combined with the fact that TikTok’s algorithm is the primary factor for what content a user sees, as opposed to friendships or follows on the big U.S. platforms, this makes TikTok a uniquely potent platform for viral propaganda.”

“I feel like lately, the videos I’m seeing are designed to get me riled up, or to emotionally manipulate me,” she said. “I get worried so now, sometimes, I find myself Googling something or checking the comments to see if it is real before I trust it.”

“I guess I don’t really know what war looks like,” she said. “But we go to TikTok to learn about everything, so it makes sense we would trust it about this too.”

a charge that could carry a sentence of up to 10 years in prison.

“Brittney has always handled herself with the utmost professionalism during her long tenure with USA Basketball,” U.S.A. Basketball said on Twitter.

The timing of the detention remains murky. Its political implications do, too.

“This follows a pattern of Russia wrongly detaining & imprisoning US citizens,” Representative Joaquin Castro, Democrat of Texas, wrote on Twitter on Saturday, citing the case of Trevor Reed, a former U.S. Marine whom a Russian court sentenced to nine years in prison in 2020 on charges of violence against police officers that his family and supporters described as fraudulent.

Ms. Griner was in Russia to play. Many W.N.B.A. stars rely on income from overseas leagues.

The financial incentives are compelling. W.N.B.A. players make a fraction of what their male counterparts do, with their maximum salary in 2022 at $228,094 while the top N.B.A. players are paid tens of millions of dollars.

Some observers criticized the gender pay gap in American basketball in connection to Ms. Griner’s detention.

“Whenever an American is detained anywhere in the world, we of course stand ready to provide every possible assistance,” Mr. Blinken said. “And that includes in Russia.”

“This is a complete misrepresentation of the definition of abuse in the family code,” Christian Menefee, the Harris County attorney, said in an interview.

“We don’t believe that allowing someone to take puberty suppressants constitutes abuse,”

Governor Abbott’s effort to criminalize medical care for transgender youth is a new front in a broadening political drive to deny treatments that help align the adolescents’ bodies with their gender identities and that have been endorsed by major medical groups.

Arkansas passed a law making it illegal for clinicians to offer puberty blockers and hormones to adolescents and banning insurers from covering care. But the law was temporarily blocked by a federal judge in July after the American Civil Liberties Union sued on behalf of four families and two doctors.

Several such bills were also introduced in Texas. None passed.

Professional medical groups and transgender health experts have overwhelmingly condemned legal attempts to limit “gender-affirming” care and contend that they would greatly harm transgender young people.

“Our nation’s leading pediatricians support evidence-based, gender-affirming care for transgender young people.”

A growing number of transgender adolescents have sought medical treatments in recent years. Transgender teenagers are at high risk for attempting suicide, according to the Centers for Disease Control and Prevention. Preliminary research has suggested that adolescents who receive such medical treatments have improved mental health.

“What is clear is that politicians should not be tearing apart loving families — and sending their kids into the foster care system — when parents provide recommended medical care that they believe is in the best interest of their child.”

“It’s designed to make parents scared,” he said. “It’s designed to make doctors scared for even facilitating gender-affirming health care.”

“Minors are prohibited from purchasing paint, cigarettes, alcohol, or even getting a tattoo,” Jonathan Covey, director of policy for the group Texas Values, said in an emailed statement. “We cannot allow minors or their parents to make life-altering decisions on body-mutilating procedures and irreversible hormonal treatments.”

She said that blocking gender-affirming care and forcing teenagers to go through the physical changes of puberty for a gender they don’t identify with was “inhumane.”

“Gender-affirming care saved my life,” they said in a statement. “Trans kids today deserve the same opportunity by receiving the highest standard of care.”

In turn, the critics say that young people can be fed increasingly extreme content or posts that diminish their self-worth.

One of the guests joining the first lady, Jill Biden, for the speech will be Frances Haugen, a former Facebook employee who leaked documents that, among other things, showed that some teenagers said Instagram made them feel worse about themselves.

But the United States lags behind many of its allies in taking concrete steps to shield children from extreme posts, addicting content and data collection online. Last year, new guidelines took effect in the United Kingdom that push platforms to limit the data they gather on young people, prompting several companies to implement more child safety features.

The Education Ministry scheduled a video lesson to be shown in schools nationwide on Thursday that described the war against Ukraine as a “liberation mission.”

Ukrainian government agencies and volunteers have published videos of disoriented Russian prisoners of war saying they had no idea they were about to be part of an invasion until just before it began, and photographs and footage showed the bodies of Russian soldiers strewn on streets and fields.

I think they themselves do not know what they are doing. They are following orders without thinking.”

“Individuals who carry out falsification must be punished in the most severe way,” said Vasily Piskaryov, a senior lawmaker in Mr. Putin’s party. “They are discrediting the absolutely rightful and understandable actions of our armed forces.”

His proposed punishment: 15 years in prison.

Tatiana Stanovaya, a scholar who has long studied Mr. Putin, wrote it was “more than logical” to expect that lawmakers this week would approve the imposition of martial law in order to block the open internet, ban all protests and restrict Russians from being able to leave the country.

There was also evidence that, even though the war took many Russians by surprise, significant numbers had come to accept it as unavoidable or forced upon Russia by an aggressive NATO. The economic crisis touched off by the West’s harsh sanctions reinforced that narrative for some.

At a Moscow shopping mall on Wednesday, a young couple lining up for cash at an A.T.M. said they opposed the war. And yet they said that the way the world was punishing them for it was not fair, either, considering that the United States had fought its own wars in recent decades without coming under harsh international sanctions.

“We understand that no armed conflict comes without victims,” Mr. Latynin said. “But this was a necessary step, because it was impossible to go on like this.”

Lawyers for Mr. Moyo attributed the adjournment to procedural delays at the outset of the trial, scheduling conflicts, and longer-than-expected witness testimony and cross-examination.

The defense lawyers have said Mr. Moyo did nothing wrong and followed proper procedures in securing the accreditation documents. They have argued that the Zimbabwe authorities have no evidence to prove the documents were faked

“The theory that was put to the witness,” Mr. Coltart said, “was that the real reason why they deported the two foreign nationals is not because they had fake accreditation cards but precisely because they wanted to prevent them from doing their work as journalists and reporting.”

Prosecutors acknowledged in court papers when Mr. Moyo was granted bail last June that their case was on “shaky ground.”

Asked if he could provide the cellphone that contained document images, Mr. Nkopilo said he no longer possessed it. Asked if he could provide a diary that the immigration authorities were required to keep of the May 8 events, Mr. Nkopilo said it had been stolen from his car.

Mr. Nkopilo asserted he had hearing problems and could not understand some of the questions, prompting a rebuke from Judge Mark Nzira, a senior justice hearing the case, who said: “I know you can hear.”

only photo images. These included an image of an image on a cellphone that had been taken on a cellphone belonging to the state’s first witness, Bothwell Nkopilo, an immigration compliance official.

“they certainly would have seized those cards as evidence of the commission of an offense.”

The Times and the Committee to Protect Journalists have criticized the prosecution of Mr. Moyo as a chilling message from the government of President Emmerson Mnangagwa on the ability of journalists to do their work.

“We are behind him and do believe, in the end, media freedom would trump,” said the group’s executive director, Reggy Moalusi. “We reiterate Moyo is a legitimate journalist and his credentials are above board. His right to practice as a journalist must be upheld and respected by Zimbabwean authorities.”

The kunga is the first known instance of a human-engineered hybrid of two species, a production far beyond the traditional processes of the domestication of animals, the researchers found.

Like mules, which are hybrids between horses and donkeys, and which were created much later, the kungas were sterile. Each new kunga was a one-off, a mating between a wild ass stallion and a donkey.

The stallions had to be captured and kept in captivity, even though they were highly aggressive, as modern records have indicated.

Kungas held their high status for at least 500 years, Dr. Geigl said. Horses did not appear until around 4,000 years ago to take their place in battle and ceremony, and to contribute to the creation of other hybrids. Before the current research, the oldest known hybrid was a mule from a site in Turkey dating to 3,000 years ago. Members of the same team reported on that find in 2020.

Archaeologists had suspected that these animals — depicted in art, their sales recorded in cuneiform writing, their bodies sometimes laid to rest in rich burial sites — were the result of some kind of crossbreeding. But proof was lacking.

Fiona Marshall, an archaeologist at Washington University in St. Louis, who has researched the prehistory of donkeys and their domestication, said the study was “enormously significant” partly because it showed that the breeders had clear intentions. The early process of domestication was always murky — probably part accident, part human intervention — but this research showed what the ancient Syrians were after.

“People wanted the qualities of a wild animal,” she said. Donkeys might have been tamer than their ancestors, the African wild ass, but the breeders in Mesopotamia wanted to back breed to other wild asses for strength and speed — and perhaps size.

the team sequenced DNA from numerous sources, including modern donkeys, horses and several species of wild asses, and museum samples.

Of particular importance were the bones of 44 kungas interred at a rich burial site in Syria called Umm el-Marra. Those skeletons had earlier led Dr. Weber and others to hypothesize that they were hybrids and that they were the kungas described in tablets and represented in art.

Their teeth showed bit marks and indicated they had been fed a special diet.

Donkeys are plentiful, of course, but the last known Syrian wild asses died in the late 1920s.
