The Islamic State (IS) group has been completely ousted from Syria's biggest eastern city, Deir az-Zor, Syrian state television reported on November 3, citing its own correspondent in the city.

Army units and support groups simultaneously regained control over the city's al-Hamidya neighborhood, the official SANA news agency said late on November 2.

The source said that army units continued their operations against the IS on the southwestern outskirts of Deir az zor, inflicting heavy losses on the ranks of the fighters and their equipment.

SANA quoted the source as saying the army's engineering units started sweeping operations to clear the newly secured neighborhoods.
