Artillery fire hit the regions of Suran and Tal El Hisn north of Aleppo, as well as Baragidah and Kusakcik, taking out three rocket installations and three vehicles in addition to killing the militants, the sources said on Sunday.
Turkey tightened a stretch of its border with ISIS-held territory in Syria in February, increasing military patrols and building more walls.
The report came shortly after Turkey’s state-run Anadolu Agency reported that US-led coalition air strikes had killed 44 Isis fighters in the Syrian areas of Harjalah, Delha, Baragitah and Hawar Kilis.
