A leading research fellow has told talkRADIO that the evacuation of Aleppo has now begun, despite an attack on an ambulance which delayed the commencement.
However Tim Eaton says those fleeing Aleppo now face fresh horror as they make an agonising choice.
Eaton, a research fellow with the Middle East and North Africa Programme at Chatham House, told Julia Hartley-Brewer: "They can either go to western Aleppo and face brutality by the regime. Or they can go to rebel-held areas already being bombed."
The situation remains tense in Aleppo despite the fresh ceasefire, and rebel sources report that at least one convoy leaving the city had shots fired at it.
Eaton warned forces need to be vigiliant in order to ensure the ceasefire holds, saying "hearing about a deal doesn’t mean it will be followed through or carried out".
