ALEPPO, Syria/BEIRUT - A new deal is being negotiated to complete the evacuation of rebel-held areas of Syria's east Aleppo which ground to a halt on Friday after demands from pro-government forces that people also be moved out of two villages besieged by insurgents.
A Syrian rebel official and a government official said early on Saturday the evacuation of Aleppo would resume and the two Shi'ite villages would be evacuated, as well as the wounded from two towns near the Lebanese border and east Aleppo.
But sources said negotiations between pro-government and opposition forces as well as their international backers, were still going on to finalize how the evacuations would take place and how many people would leave.
The chaos surrounding the evacuation reflects the complexity of Syria's civil war, with an array of groups and foreign interests involved on all sides.
Aleppo had been divided between government and rebel areas in the nearly six-year-long war, but a lightning advance by the Syrian army and its allies began in mid-November following months of intense air strikes, forcing the insurgents out of most of the rebel-held territory within a matter of weeks.
A senior Syrian rebel official from the powerful Ahrar al Sham group involved in the talks on Saturday said the deal was being held up by Iran and its allied Shi'ite militias which were insisting people be allowed to leave the besieged Shi'ite villages of Kefraya and al-Foua before allowing the Aleppo evacuation to proceed.
"Iran and its sectarian proxies are using the humanitarian situation of our people in besieged Aleppo and preventing civilians from leaving until the evacuation of their groups in al-Foua and Kefraya," Munir Sayal, the head of the political wing of the movement, told Reuters in a telephone interview.
Al Farouk Abu Bakr, the head rebel negotiator inside Aleppo charged with negotiating on their behalf, earlier said an agreement was reached that included the two Shi'ite villages as demanded by Iran. But he said later that Tehran had once again obstructed a deal.
As darkness fell on Saturday afternoon and temperatures began to fall below freezing, there was no sign the evacuation was happening. A resident in Aleppo told Reuters that nobody had left the rebel-held enclave and no buses had entered. He also said he had heard gunfire near where people were to wait for the buses.
The International Committee of the Red Cross (ICRC) said thousands of cold, scared and injured people were still in east Aleppo waiting to leave. It said it had received some indications that a deal would be reached soon.
The Syrian government official, part of the team negotiating the evacuations, said: "It was agreed to resume evacuations from east Aleppo in parallel with the evacuation of (medical) cases from Kefraya and al-Foua and some cases from Zabadani and Madaya."
The towns of Madaya and Zabadani are blockaded by pro-government forces.
The operation to evacuate fighters and civilians from the last opposition-held area of Aleppo was suspended on Friday, its second day, after pro-government militias demanded that the wounded also be brought out of al-Foua and Kefraya, and protesters blocked a convoy on the road out of Aleppo.
Another Free Syrian Army official Zakaria Malhafji said that he expected the Aleppo evacuation to resume on Sunday after reaching an agreement that also includes simultaneous evacuation from the two Shi'ite villages.
"Tomorrow morning the evacuation from Aleppo will begin again," Malhafji told TV news channel al-Arabiya al Hadath.
BEATEN AND ROBBED
Numerous activists, rebels and east Aleppo residents shared reports and videos of people fleeing amid chaos, the sound of shooting, being detained and returning home badly beaten and robbed of their possessions near a checkpoint as they tried to leave the city on Friday.
Rebels said the previous evacuation deal was breached by pro-government, Iran-backed militias who detained "hundreds" of people trying to leave, leading to some deaths. A Syrian military source denied this, but said a convoy trying to leave was sent back.
"Now we are working on international guarantees to guarantee the safety of those who leave Aleppo so that such violations are not repeated," Syrian rebel negotiator Abu Bakr told al-Arabiya from Aleppo on Saturday.
The Syrian Arab Red Crescent (SARC) and the ICRC said guarantees were needed to protect people.
"We're ready to resume facilitating the evacuation according to our humanitarian mandate. But we now expect all the parties on the ground to provide us with solid guarantees in order to keep the operation going," said Marianne Gasser, head of the ICRC in Syria.
NO EVACUATIONS ON SATURDAY
A military news outlet run by Hezbollah, an ally of Damascus, had said evacuation buses were heading to the two villages to complete the evacuations and said this could happen on Saturday.
But the Syrian Observatory for Human Rights, which monitors the war, said the evacuations in al-Foua or Kefraya, where it says there are around 20,000 people - of whom roughly 4,500 are pro-government fighters - was postponed and would begin on Sunday.
It was expected that 50 buses would take around 1,500 people, including wounded, to government-held areas.
The Observatory said 8,000 people, including some 3,000 fighters and more than 300 wounded, had left Aleppo in convoys of buses and ambulances in the evacuations that began on Thursday morning.
Rebel officials say the numbers evacuated are much lower, with no fighters having left.
The United Nations says around 30,000 people remain in rebel-held Aleppo, of whom a number would be taken to Idlib province, which is mostly controlled by hardline Islamist groups, and the rest would go to government-held city districts.
Idlib is already a target for Syrian and Russian air strikes, but it is unclear whether 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.
The Observatory said war planes bombed insurgent-controlled areas west of Aleppo overnight and north of Aleppo on Saturday.
Syrian state media reported on Saturday that a number of fighters south of Damascus had surrendered their weapons to the state in the towns of Zakiya and al-Deirkheyba as part of local truces.
Through a series of so-called settlement agreements and army offensives, the Syrian government, backed by Russian air power and Iran-backed militias, has been steadily suppressing armed opposition in the suburbs of the capital.
Russian President Vladimir Putin, Syria's most powerful ally, said on Friday 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.
A senior Syrian opposition leader, Riyad Hijab, said he was willing to attend the talks if the aim was to set up a transitional government. Assad has ruled out stepping down as part of a political solution to the war.
Aleppo, a once-flourishing economic center with renowned ancient sites, has been pulverized 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.
Even with victory for Assad in Aleppo, the war will be far from over. Insurgents still retain the rural stronghold of Idlib province as well as other territory in western, northern and southern Syria, while the jihadist Islamic State militant group holds swathes of the east and recaptured the ancient city of Palmyra earlier this week.
