The evacuation of people from the last opposition-held areas of the Syrian city of Aleppo was suspended on Friday after pro-government militias demanded that the wounded should also be brought out of two Shi’ite villages being besieged by rebel fighters.

The second day of the operation to evacuate Aleppo’s rebel enclave ground to a halt amid recriminations from all sides after a morning that had seen the pace of the operation pick up.

Rebel sources accused pro-government Shi’ite militias of opening fire on bus convoys taking evacuees out of the city.

A Syrian official source said the evacuation was halted because rebels had sought to take out people they had abducted with them, and they had also tried to take weapons hidden in bags. This was denied by Aleppo-based rebel groups.

But a media outlet run by the pro-government Hezbollah group said protesters had blocked the road from the city, demanding that wounded people from the villages of Foua and Kefraya in nearby Idlib province should also be evacuated.

It also said rebels had bombarded a road due to be used by buses to conduct the evacuation from the Shi’ite villages.

Iran, one of Syria’s main allies, had demanded that the villages be included in a ceasefire deal under which people are leaving Aleppo, rebel and United Nations officials have said.

There has been no sign of any evacuation from the villages, which have long been besieged by insurgents in the mostly rebel-held province.

Aid agencies involved in the Aleppo evacuation had been told to leave the area without explanation after the operation was aborted, the World Health Organization said.

CARS AND BUSES

Earlier, private cars had been allowed to leave Aleppo along with convoys of buses evacuating rebel fighters and civilians.

The Syrian Observatory for Human Rights, a monitoring group, said a total of 8,000 people, including some 3,000 fighters and more than 300 wounded, had left the city in convoys of buses and ambulances since the evacuation began on Thursday morning.

Photos sent by an activist waiting to leave the rebel-held sector of east Aleppo showed crowds of people in thick coats in a street lined with flattened buildings in the cold winter air.

Private cars and minibuses with bundles strapped to their roofs filled the street, as people sat on rubble or stood next to bags of their belongings.

In a message sent to journalists, the activist said children were “hungry and crying” and people were “exhausted”, not knowing if buses would arrive to take them out.

By early Friday morning, nearly 200 evacuated patients had arrived in eight “overwhelmed” hospitals in government-held western Aleppo, Idlib and Turkey, according to the WHO.

The United Nations says 50,000 people remain in rebel-held Aleppo, of whom about 10,000 would be taken to Idlib province and the rest would go to government-held city districts.

Idlib province, mostly controlled by hardline Islamist groups, is not a popular destination for fighters and civilians from east Aleppo, where nationalist rebel groups predominated.

Idlib is already a target for Syrian and Russian air strikes but it is unclear if the government will push for a ground assault or simply seek to contain rebels there for now.

Turkey has said Aleppo evacuees could also be housed in a camp to be constructed near the Turkish border to the north.

Two potential sites just inside Syria have been identified to set up a camp, which could host up to 80,000 people, Turkish officials said, adding that they expected up to 35,000 people to come. Turkey would continue to accept sick and wounded coming from Aleppo.

PUTIN SEEKS CEASEFIRE

Aleppo had been divided between government and rebel areas in the nearly six-year civil war, but a lightning advance by the Syrian army and its allies that began in mid-November deprived the insurgents of most of their territory in a matter of weeks.

Russian President Vladimir Putin, Syria’s most powerful ally, said he was working with Turkish President Tayyip Erdogan to try to start a new round of Syrian peace talks aimed at securing a nationwide ceasefire.

Speaking in Japan, Putin said the new talks, if they happened, could be held in Kazakhstan and would complement U.N.-brokered negotiations that have been taking place intermittently in Geneva.

“The next step is to reach an agreement on a total ceasefire across the whole of Syria. We are conducting very active negotiations with representatives of the armed opposition, brokered by Turkey,” the Russian leader said.

Aleppo, a once-flourishing economic centre with its renowned ancient sites has been pulverised during the war that has killed more than 300,000 people, created the world’s worst refugee crisis and allowed for the rise of Islamic State.

The United States was forced to watch from the sidelines as the Syrian government and its allies, including Russia, mounted an assault to pin down the rebels in an ever-diminishing pocket of territory, culminating in a ceasefire this week.

U.S. Secretary of State John Kerry said on Thursday that the Syrian government was carrying out “nothing short of a massacre” in Aleppo.

French Foreign Minister Jean-Marc Ayrault said the U.N. Security Council would meet on Friday to discuss a quick deployment of U.N. observers to east Aleppo to ensure there were no atrocities and that humanitarian aid reached the city.

The Syrian White Helmets civil defence group and other rights organizations accused Russia of committing or being complicit in war crimes in Syria, saying Russian air strikes in the Aleppo region had killed 1,207 civilians, including 380 children.

A senior Russian general said on Thursday that the Syrian army had almost finished its operations in Aleppo.

But the war will still be far from over, with insurgents retaining their rural stronghold of Idlib province, and the jihadist Islamic State group holding swathes of the east and recapturing the ancient city of Palmyra this week.
