TEHRAN (Press Shia Agency) – After breaking a Daesh (ISIL) siege, Syria’s army is seeking to encircle the remaining militant-held parts of Deir ez-Zor city, a military source said Wednesday.

"The army is seeking to encircle Daesh from three sides by controlling the parts of the western bank of the Euphrates river," the source told AFP.

The army has brought reinforcements to the city and is seeking to oust Daesh from eastern neighborhoods that run along the Euphrates river, which slices diagonally through the province.

Troops would target riverside territory on the city's northwestern edges as well as strategic areas on its southern outskirts, including the key military airport and the village of Al-Jafra, on the banks of the Euphrates.

The operation seeks to "oust Daesh from the city and the province completely," the military source added.

Last week, Syria's army and allied fighters broke a years-long Daesh siege of Deir ez-Zor, entering two regime-held sections of the city that had been cut off from each other.
