The evacuation of east Aleppo has been halted, with Syrian rebels accused of failing to respect a deal to lift their own siege of two pro-government towns.
At least 6,000 civilians and rebels are said to have left Aleppo, Syria’s largest city, since Thursday after the government recaptured most of the city.
But the UN believes that some 50,000 people are still trapped there.
Under a deal brokered by Russia and Turkey, the rebels were meant to ease their siege of towns in Idlib province.
Reports suggest the biggest rebel group in Idlib, the Jabhat Fateh al-Sham jihadists formerly known as the Nusra Front, have now agreed to allow injured people to leave the towns, Foua and Kefraya, which are home to some 20,000 people.
Four years of vicious fighting in eastern Aleppo left thousands dead, destroyed hospitals and wiped out food supplies.
Those being evacuated were taken in convoys to rebel-held parts of Idlib.
Meanwhile, there were new protests across the world, from Malaysia to Turkey, to condemn violence against Syrian civilians and show solidarity with the country’s opposition.
