Syria’s Al-Qaeda affiliate and allied rebels pushed offensives around northern, central and coastal Syria Monday, triggering a spike in violence that could threaten a truce ahead of peace talks, activists said.
ISIS also took back control of the town of Al-Rai near Turkey, which rival rebels had captured last week, the Syrian Observatory for Human Rights said.
Neither the Al-Qaeda-affiliated Nusra Front nor ISIS are included in a truce brokered by the United States and Russia that came into force on Feb. 27.
But the fact that rebels are fighting alongside Nusra in such a broad offensive, while government forces push back, has sparked concerns over the durability of the shaky truce.
