The militants hit with mortar fire a security checkpoint for the YPG at the southern entrance of Ain Issa town in the northern countryside of Raqqa.
At least two Kurdish fighters were killed before clashes broke out between the YPG and IS jihadists in the vicinity of Ain Issa.
Speaking to ARA News, YPG official Habun Osman said that the clashes continued until Sunday midnight, when the militants were forced to retreat towards their positions inside Raqqa.
“At least four IS terrorists were killed and several others were wounded in the clashes, where heavy machine guns were used by our forces to deter the terror attack on Ain Issa,” Osman said.
“The terrorists were eventually forced to withdraw from the area under heavy blows by our (YPG) units,” he added.
In a bid to retake the town, the radical group has launched several offensives on the YPG positions after the Kurdish forces retook the control of the city from the militants nearly eight months ago.
