Syria war: Russians killed in militant raid in Deir al-Zour

At least four Russian combatants have been killed by militants in the eastern Syrian province of Deir al-Zour.

Two military advisers died when the Syrian army battery they were directing was attacked. Five other Russians were injured and two died later of their wounds, the defence ministry said.

Syria’s army took Deir al-Zour city last November but Islamic State fighters remain
