US State Department and military leaders of the global coalition vowed to support local authorities in Deir Ezzor during a meeting with leaders of the Deir Ezzor Military and Civil councils.
The meeting, held in Omar oil field base, discussed the latest field developments, ways to combat terrorism and security operations against ISIS cells.
It also addressed the possibility of expanding military operations to eliminate sleeper cells that target military and civilian leaders and officials of the Civil Administration in Deir Ezzor in eastern Syria.
The spokeswoman of the Military Council, Lilwa Abdullah, said they discussed the assassination attempts of local figures and leaders from the region.
Abdullah indicated that the US and coalition officials vowed to continue providing logistical and military support, as well as ways to support the infrastructure of the region.
On Saturday, a military convoy of the global coalition forces entered the Syrian territories via al-Walid border crossing. The convoy consisted of 35 trucks carrying logistical and military support to the coalition bases in the southern countryside of Hasakeh.
Meanwhile, a security leader of the internal security forces of the US-backed Syrian Democratic Forces (SDF) was killed by unknown gunmen in the town of Dhiban, east of Deir Ezzor.
Military sources accused ISIS sleeper cells of carrying out the operation.
Last Thursday, five SDF members were killed by an explosive device that detonated as their military vehicles approached during a patrol to inspect the oil fields.
The Syrian Observatory for Human Rights reported that the number of those who were killed or assassinated in SDF areas has risen to 600 since the forces took control of the cities and towns of Deir Ezzor, bordering Iraq.
On Friday, the global coalition and SDF carried out a wide-scale security operation in Deir Ezzor, raiding a number of towns in the northern and eastern countryside.
The forces captured 20 people, all of whom were displaced from areas controlled by the Syrian regime. They also arrested a prominent SDF military official, Abu Fahd Khasham, along with two of his brothers.
