IS is the city of Deir al-Zor

Islamic state combat units have attacked the Eastern Syrian city Deir al-Zor on Sunday night with a heavy gun.

IS has been serving in most of the province of Deir al-Zor for two years, but the same city and the nearby airport are in the hands of the government forces of President Bashar al-Assad. The Syrian Air Force regularly sheds out auxiliaries with Russian support over the surrounding area, where about 200,000 people live. There is a lack of food and medicine.
