Mr. Hassi also dismissed recent footage released by the Islamic State group, also known as ISIS or ISIL, showing the beheading of a group of Egyptian Christians

He said it was “a fabricated Hollywood-like video” concocted by his opponents “to create divisions between us and the Egyptian people,”

Libya looked like the latest fragile blossoming of the Arab spring

Army commanders, mostly of Arab Bedouin origin, refused orders to shoot the protesters

the revolutionaries cobbled together a National Transitional Council (NTC) claiming to represent all of Libya

Volunteers from students to bank managers took up arms, joining popular militias and only sometimes obeying the orders of defecting army commanders trying to take control

In August Western bombing of government bases surrounding Tripoli cleared an avenue for the revolutionaries to take the capital.

Recognised abroad, popular at home and enjoying the benefits of healthy oil revenues—97% of the government’s income—the NTC was well placed to lay the foundations for a new Libya

he judges, academics and lawyers who filled its ranks worried about their own legitimacy and feared confrontation with the militias which, in toppling Qaddafi, had taken his arsenals for their own.

militia leaders were already ensconced in the capital’s prime properties

The NTC presided over Libya’s first democratic elections in July 2012, and the smooth subsequent handover of power to the General National Congress (GNC) revived popular support for the revolution.

Islamist parties won only 19 of 80 seats assigned to parties in the new legislature, and the process left the militias on the outside

The Homeland party, founded by Abdel Hakim Belhad

tried to advertise its moderation by putting an unveiled woman at the head of its party list in Benghazi

The incumbent prime minister, Abdurrahim al-Keib, a university professor who had spent decades in exile, fretted and dithered

He bowed to militia demands for their leaders to be appointed to senior ministries, and failed to revive public-works programmes

which might have given militiamen jobs

Many received handouts without being required to hand in weapons or disband, an incentive which served to swell their ranks

the number of revolutionaries registered with the Warriors Affairs Commission set up by the NTC was about 60,000; a year later there were over 200,000. Of some 500 registered militias, almost half came from one city, Misrata.

In May 2013 the militias forced parliament to pass a law barring from office anyone who had held a senior position in Qaddafi’s regime after laying siege to government ministries.

In the spring of 2014, Khalifa Haftar, a retired general who had earlier returned from two decades of exile in America, forcibly tried to dissolve the GNC and re-establish himself as the armed forces’ commander-in-chief in an operation he called Dignity

The elections which followed were a far cry from the happy experience of 2012. In some parts of the country it was too dangerous to go out and vote

Such retrenchment has been particularly noticeable among women. In 2011 they created a flurry of new civil associations; now many are back indoors.

Turnout in the June 2014 elections was 18%, down from 60% in 2012, and the Islamists fared even worse than before

Dismissing the results, an alliance of Islamist, Misratan and Berber militias called Libya Dawn launched a six-week assault on Tripoli. The newly elected parliament decamped to Tobruk, some 1,300km east

Grasping for a figleaf of legitimacy, Libya Dawn reconstituted the pre-election GNC and appointed a new government

So today Libya is split between two parliaments—both boycotted by their own oppositions and inquorate—two governments, and two central-bank governors.

The army—which has two chiefs of staff—is largely split along ethnic lines, with Arab soldiers in Arab tribes rallying around Dignity and the far fewer Misratan and Berber ones around Libya Dawn.

Libya Dawn controls the bulk of the territory and probably has more fighters at its disposal.

General Haftar’s Dignity, which has based its government in Beida, has air power and, probably, better weaponry

the Dignity movement proclaims itself America’s natural ally in the war on terror and the scourge of jihadist Islam

The struggle over the Gulf of Sirte area, which holds Libya’s main oil terminals and most of its oil reserves, threatens to devastate the country’s primary asset

And in the Sahara, where the largest oilfields are, both sides have enlisted ethnic minorities as proxies

ibya Dawn has drafted in the brown-skinned Tuareg, southern cousins of the Berbers; Dignity has recruited the black-skinned Toubou. As a result a fresh brawl is brewing in the Saharan oasis of Ubari, which sits at the gates of the al-Sharara oilfield, largest of them all.

Even under Qaddafi the country did not feel so cut off

The UAE’s Gulf rival, Qatar, and Turkey have backed the Islamists and Misratans in the west

If oil revenues were to be put into an escrow account, overseas assets frozen and the arms embargo honoured he thinks it might be possible to deprive fighters of the finance that keeps them fighting and force them to the table

Until 1963 Libya was governed as three federal provinces—Cyrenaica in the east, Fezzan in the south and Tripolitania in the west

The old divisions still matter

the marginalised Cyrenaicans harked back to the time when their king split his time between the courts of Tobruk and Beida and when Arabs from the Bedouin tribes of the Green Mountains ran his army

Tensions between those tribes and Islamist militias ran high from the start.

July 2011 jihadists keen to settle scores with officers who had crushed their revolt in the late 1990s killed the NTC’s commander-in-chief, Abdel Fattah Younis, who came from a powerful Arab tribe in the Green Mountains. In June 2013 the Transitional Council of Barqa (the Arab name for Cyrenaica), a body primarily comprised of Arab tribes, declared the east a separate federal region, and soon after allied tribal militias around the Gulf of Sirte took control of the oilfields.

In the west, indigenous Berbers, who make up about a tenth of the population, formed a council of their own and called on larger Berber communities in the Maghreb and Europe for support

Port cities started to claim self-government and set up their own border controls.

Derna—a small port in the east famed for having sent more jihadists per person to fight in Iraq than anywhere else in the world

opposed NATO intervention and insisted that the NTC was a pagan (wadani) not national (watani) council

Some in Derna have now declared their allegiance to Abu Bakr al-Baghdadi, the caliph of the so-called Islamic State (IS) in Syria and Iraq.

In December the head of America’s Africa command told reporters that IS was training some 200 fighters in the town.

an escalating war among its patchwork of rival cities and tribes.

Motorists wait in lines stretching more than three miles at shuttered gas stations, waiting for them to open. Food prices are soaring, uncollected garbage is piling up in the streets and bicycles, once unheard-of, are increasingly common.

many Libyans despaired of any resolution

In Benghazi, Libya’s second-largest city, the fighting has closed both its airport and seaport, strangling the city.

the rush toward war is also lifting the fortunes of the Islamist extremists of Ansar al-Shariah, the Benghazi militant group.

The United Nations, the United States and the other Western powers have withdrawn their diplomats and closed their missions

“We cannot care more than you do,” the British ambassador, Michael Aron, wrote

Until now, a rough balance of power among local brigades had preserved a kind of equilibrium, if not stability

the transitional government scarcely existed outside of the luxury hotels where its officials gathered, no other force was strong enough to dominate. No single interest divided the competing cities and factions.

But that semblance of unity is now in tatters, and with it the hope that nonviolent negotiations might settle the competition for power and, implicitly, Libya’s oil.

In May, a renegade former general, Khalifa Hifter, declared that he would seize power by force to purge Libya of Islamists, beginning in Benghazi. He vowed to eradicate the hard-line Islamists of Ansar al-Shariah, blamed for a long series of bombings and assassinations.

General Hifter also pledged to close the Parliament and arrest moderate Islamist members

he has mustered a small fleet of helicopters and warplanes that have bombed rival bases around Benghazi, a steep escalation of the violence.

moderate Islamists and other brigades who had distanced themselves from Ansar al-Shariah began closing ranks, welcoming the group into a newly formed council of “revolutionary” militias

a broad alliance of Benghazi militias that now includes Ansar al-Shariah issued a defiant statement denouncing relative moderates like the Libyan Muslim Brotherhood. “We will not accept the project of democracy, secular parties, nor the parties that falsely claim the Islamic cause,”

the general’s blitz has now stalled, it polarized the country, drawing alarms from some cities and tribes but applause from others.

the loudest applause came from the western mountain town of Zintan, where local militia leaders had recruited hundreds of former Qaddafi soldiers into special brigades

the rival coastal city of Misurata, where militias have allied with the Islamists in political battles and jostled with the Zintanis for influence in the capital

the Misurata and Islamist militias developed a reputation for besieging government buildings and kidnapping high officials to try to pressure the Parliament. But in recent months the Zintanis and their anti-Islamist allies have stormed the Parliament and kidnapped senior lawmakers as well.

the newly elected Parliament, led at first, on a seniority basis, by a member supportive of Mr. Hifter, announced plans to convene in Tobruk, an eastern city under the general’s control.

About 30 members, most of them Islamists or Misuratans, refused to attend,

Tripoli’s backup airport, under the control of an Islamist militia, has cut off flights to Tobruk, even blocking a trip by the prime minister.

a spokesman for the old disbanded Parliament, favored by the Islamists and Misuratans, declared that it would reconvene in Tripoli

In Tobruk, a spokesman for the new Parliament declared that the Islamist- and Misuratan-allied militias were terrorists, suggesting that Libya might soon have two legislatures with competing armies

Each side has the support of competing satellite television networks financed and, often, broadcast from abroad, typically from Qatar for the Islamists and from the United Arab Emirates for their foes.

Hassan Tatanaki, a Libyan-born business mogul who owns one of the anti-Islamist satellite networks, speaking in an interview from an office in the Emirates. “We are in a state of war and this is no time for compromise.”

Fighters and tribes who fought one another during the uprising against Colonel Qaddafi are now coming together on the same side of the new fight, especially with the Zintanis against the Islamists. Some former Qaddafi officers who had fled Libya are even coming back to take up arms again.

“It is not pro- or anti-Qaddafi any more — it is about Libya,” said a former Qaddafi officer in a military uniform

Beneath the battle against “extremists,” he said, was an even deeper, ethnic struggle: the tribes of Arab descent, like the Zintanis, against those of Berber, Circassian or Turkish ancestry, like the Misuratis. “The victory will be for the Arab tribes,”

The new Libyan House of Representatives, which was elected in June, has formally announced its alliance with Hifter on Monday

But other Arab nations are intervening directly in the conflict.

Hifter would now lead Libyan army soldiers as well in the fight against the Islamist militias.

Operation Dawn, seized Tripoli in August, parliament and the rest of the government have all decamped to faraway Tobruk, in the eastern end of the country close to Egypt.  

Egyptian officials told the Associated Press that Egyptian warplanes, operated by Libyan pilots, were bombing Islamist militias in Libya. Both Libyan and Egyptian officials later denied those reports, and aviation experts said it was highly unlikely that Libyan pilots would have the skills needed.   On Monday, the presidents of Egypt and Sudan said they would support the Libyan military.  

Prime Minister Abdullah al Thinni is planning to visit Moscow to seek Russian support for the army.  

Libya's Prime Minister Ali Zeidan

The country's prime minister recently called on western powers to help him stop the spread of what he calls 'militancy' in his country.

There are more than 225,000 Libyans registered in militias. They receive state salaries but often act outisde of government control, taking orders from local or political commanders.

Groups in Libya's eastern Cyrenaica region and in the southern Fezzan region have called for independence

In Cyrenaica, former rebel leader Ibrahim al-Jathran and his 20,000 men strong militia say they now run local affairs, with Jathran and his men controlling facilities that account for 60 percent of Libya's oil wealth.

Mr Pack points out that the country has three main power blocks: Libya Dawn (a mixture of Islamist and non-Islamist militias allied with the Tripoli-based government), Operation Dignity (led by forces loyal to General Khalifa Haftar and allied with the internationally recognised government based in the eastern city of Tobruk) and Jihadist groups (which include IS, al-Qaeda and Ansar al-Sharia - the most powerful of them). "There is a civil war between the two main groups [Libya Dawn and Operation Dignity]. The jihadists act as spoilers," Mr Pack says.
