Hundreds of children held by IS in besieged prison in Syria

Fears are growing over the fate of hundreds of children believed to be held by jihadist extremists inside a besieged prison in north-east Syria.

Nearly 850 children are inside Ghwayran prison in Hasaka, which was stormed by Islamic State (IS) group fighters on Thursday, triggering days of battles.

On Monday some 300 militants in the prison gave up, security forces said.
