Clashes have been reported in northeastern Syria for more than three days after Islamic State (Isis) militants tried to break out suspected extremists from a Kurdish-run prison.
On Thursday, more than 100 Isis fighters attacked the Gweiran prison in Hassakeh, trying to free over 3,000 allies held by US Syrian Democratic Forces (SDF). The fighters killed 17 members of the security forces. At least 70 inmates have also died in the attack.
