Footage filmed on Tuesday allegedly shows what Syrian Democratic Forces (SDF) described as Islamic State (IS, formerly ISIS/ISIL) militants and their family members surrendering near the last IS stronghold in Syria, Baghouz.
Scores of injured men, women and children are filmed being helped up the mountainside. Later food is distributed amongst them and they are driven off on vans and trucks.
This follows Baghouz being heavily pounded by the coalition forces overnight.
Head of the SDF Press Office in northern Syria, Mustafa Bali, said on twitter that 3,000 IS fighters and their families surrendered to the SDF since Monday.
The SDF says the operation against the last IS stronghold started on March 1, after nearly 15,000 IS members surrendered with their families. It was then paused on March 4, as more wanted to surrender.
It is estimated that up to 10,000 IS members and their families surrendered between March 4 and 10, according to the SDF.
