The Islamic State (IS) group claimed its first attack on Syria’s new government forces since the fall of longtime Syrian President Bashar al-Assad on Thursday, two war monitors said.

SITE Intelligence Group said it was the first IS-claimed attack on Syria’s new government, with the Syrian Observatory for Human Rights saying that one person was killed and three members of the Syrian army’s 70th division injured when their patrol was hit by a remotely detonated landmine on Wednesday.
