The Turkish military stated that shelling by Turkish artillery and drones which were launched from southern Turkey struck ISIS targets in Syria on Sunday, killing 34 militants.

Turkish howitzers and multiple rocket launchers first hit ISIS targets about 12 km (seven miles) south of the border, then four drones that took off from the Incirlik base in southern Turkey destroyed further targets, the military explained.

The strikes, which destroyed six vehicles and five gun positions for ISIS, came in retaliation to ISIS rocket attacks on Sunday when four rockets fired from Syria hit the Turkish border town of Kilis and wounded eight people

The border town of Kilis and surrounding area has been hit frequently by rocket fire from ISIS-controlled Syrian territory in recent months, killing civilians.

Turkey has repeatedly fired back at ISIS positions under its rules of engagement, but has called for greater support from Western allies, citing the difficulty of hitting moving targets with howitzers.

In the past year, Turkey has also witnessed suicide bombings linked to the ISIS as well as attacks linked to Kurdish militants.

The latest came Sunday, when a car bomb detonated outside a police station in the southern city of Gaziantep, near Syria. There was no immediate claim of responsibility for that attack but anti-terrorism units raided 20 Gaziantep addresses overnight in search for suspects.

Foreign Minister Mevlut Cavusoglu was quoted as saying last week that the United States would deploy a rocket launcher system near the stretch of border that has come under attack. A senior U.S. military official confirmed the matter was under discussion but declined to comment further.
