DAMASCUS, July 18 (Xinhua) -- Two explosions targeted positions of the Kurdish People's Protection Units (YPG) in the countryside of Syria's northeastern city of Hasakah on Tuesday, killing at least four people, a well-informed source in the city told Xinhua.
The first bombing was caused by a booby-trapped car, which tore through a checkpoint of the YPG in the town of Manajeer in the western countryside of Hasakah, killing two civilians and two YPG fighters, the source said on condition of anonymity.
The second blast rocked the village of Mabrukeh, in the western countryside of Ras al-Ein city in Hasakah countryside, leaving unknown losses.
No party has claimed responsibility for both bombings, but the Kurdish militias have two enemies in the north.
The first is the Islamic State (IS) group, which has carried out several bombings in Hasakah against the YPG. The second enemy is the Turkish-backed rebels, who are amassing to fight the Kurdish groups in northern Syria near the Turkish borders.
Ankara has been opposing any influence of the Kurdish groups near its borders, prompting to recruit Syrian rebels to stop the progress of the Kurdish fighters in the north, particularly following the advance made by the Kurdish-led fighters in the war on IS in the city of Raqqa in northern Syria.
