The Turkish military killed on Tuesday 13 Daesh terrorists in retaliation fire after four rockets launched from Daesh-held northern Syrian territory fell near a Turkish military border post in southern Kilis province.

Military sources said that security forces targeted Daesh positions where the rockets were launched from after they were determined by radars. Four Daesh vehicles, two of which had Soviet brand DShK 1938 machine guns on top, and three gun emplacements were also destroyed.

Turkey has been under indiscriminate rocket attacks from Syria since mid-January.

In the province of Kilis alone, a total of 18 people have been killed and 60 others have been wounded as a result.

The distance between Kilis city center and the Syrian border is less than four kilometers in some areas.

The rockets are believed to have been fired from a Daesh-controlled region in Syria, where Daesh and Syrian opposition have been fighting to expand their control over the territory between the towns of Azaz and al-Rai since early April.

Occasional stray rockets and mortars land in southern and southeastern Turkey due to the conflict in neighboring Syria. Despite a ceasefire in the country, violence still persists in the area.

Kilis, which is home to large numbers of Syrian refugees exceeding its own population, has suffered repeatedly from cross-border shelling. The rockets became an almost daily occasion in the small town where locals recently rallied for more security measures.

Under Turkey's rules of engagement, the military responds immediately by shelling Daesh positions in Syria.
