The evacuation of rebel fighters and civilians, including the wounded, from rebel-held areas of Aleppo has gathered pace.
At least 6000 people have left parts of the Syrian city in several convoys of buses and ambulances in the past 24 hours, under a ceasefire that would see the government retake the city.
Those evacuated included some 900 wounded, both fighters and civilians.
There was no sign, however, of evacuations from two villages besieged by rebels in neighbouring Idlib province, which were to be included in the deal.
Aleppo was divided between government and rebel areas of control in the nearly six-year civil war.
A lightning advance by the Syrian army and its allies, which began in mid-November, meant the insurgents lost most of their territory in a matter of weeks.
The European Council president Donald Tusk today admitted the European Union was not effective enough in trying to stop what he called the tragedy of Aleppo and other parts of Syria.
Speaking at the end of a summit of European leaders, Mr Tusk acknowledged the EU's inability to stop the conflict, but rejected criticism that it was to blame.
He said the EU was the biggest contributor of humanitarian assistance to Syrians.
