Syrian government forces and their allies have recaptured territory from Islamic State in countryside southeast of its stronghold Raqqa after air strikes in the area, a pro-Damascus military media unit and war monitors reported. The advances towards the provincial boundary between Raqqa and Deir al-Zor took place late on Saturday, the media unit, run by Damascus ally Lebanese Hezbollah, and the British-based Syrian Observatory for Human Rights said. The army seized an oil field in the Sabkha area as part of the advance.
