Two members of the Washington-sponsored militia lost their lives and at least three were injured in an ambush with explosives against their armored vehicle in the town of Al-Sour in the northeast of the Deir Ezzor province, on Friday, according to national television.
Likewise, unidentified armed individuals opened fire with machine guns at a school that the group converted into a barracks in the city of Al-Shuhel.
The action, which caused casualties and material damage, occurred after the militia had seized at least 10 homes close to their headquarters and those of the US occupation forces.
The majority Kurdish force dominates most of the oil-rich Syrian region of Al-Jazeera and receives weapons, money and training from Washington.
Practices such as the compulsory recruitment of young people, servility to the United States, the theft of oil and crops, as well as the eviction of families from their homes due to their proximity to the US bases, have provoked the indignation of residents, who increased their actions of protest and armed resistance against the group.
