Daesh laid siege to a military airport which is under the control of Syrian regime forces in the city of Deir ez-Zor yesterday, as forces loyal to President Bashar Al-Assad struggle to maintain any effective presence in the eastern Syrian city.
After days of fierce fighting, Daesh fighters managed to cut off all supply routes and divide the territories held by the Assad regime while taking control of important sites in the vicinity of the airbase.
Deir ez-Zor, which is the largest city in the eastern part of Syria,has long been under siege by Daesh.
However, the Syrian army forces were in control of certain neighbourhoods, including the city's airport. For long periods residents of Deir ez-Zor and the servicemen needed air drops for food and essential supplies.
The military airbasehas been described as a "small island" surrounded by the territories under Daesh control. Since opposition forces took control of the region in 2014, militants made countless attempts to take control and besiege the airbase but had failed to take full control.
Safa news agency reported a military official who commented on the latest siege of the military airport saying that "this attack was the fiercest onslaught initiated by [Daesh] on the airport and the region."
Daesh has now successfully cut through the only land supply route between the base and Deir ez-Zor.
If Daesh manages to control the airbase and Deir ez-Zor,it will be seen as a bigger blow to the regime than its defeat in Palmyra which, unlike Deir ez-Zor did not have an airbase with Syrian forces to defend it.
