According to reports broadcast by state television, popular resistance groups attacked the SDF headquarters in the city of Al-Basira, in Deir Ezzor province, 432 km northeast of Damascus.
State television claims that RPG howitzers and machine guns were used in this attack, which destroyed part of the headquarters (possible casualties have not been confirmed yet).
Moreover, three members of that illegal group were killed in a bomb attack on a vehicle on the road between the provinces of Raqa and Hasakeh, according to activists the local website Athr Press reported.
Meanwhile, unknown armed men assassinated the head of SDF general security in Al-Hol city, east of Hasakeh province.
That group, mostly Kurdish, controls most of the Syrian Al-Jazira region, rich in oil, and receives weapons and training from Washington.
Practices such as the conscription of young people, servility to the United States, oil and crop thefts, and the eviction of families that live near US military bases have outraged settlers, who have increased their protests and resistance against that group.
