More than 200 people have reportedly been killed in northeast Syria as a fifth day of fighting rages on between US-backed Syrian forces and suspected Islamic State militants following an attack on a prison housing thousands of extremists.
The brazen assault by Isis fighters on Gweiran prison in the northeastern city of Hassakeh on Thursday is one of the deadliest since the militant group’s so-called caliphate was declared defeated by a US-led coalition nearly three years ago.
