The military says a Turkish soldier was killed from shots fired from Islamic State-controlled area across the border in Syria. A second soldier is reported missing.

The military said the incident occurred Tuesday at a border post near the town of Kilis. The soldier disappeared following a clash between the soldiers and the assailants.

On Saturday, Turkey announced that its fighter jets carried out their first airstrikes as part of the U.S.-led coalition against IS, attacking extremist targets deemed to be a threat to Turkey.

Turkey agreed to take on a more active role against the radical group in July following a suicide bombing, blamed on IS, which killed 33 people near the Turkish-Syrian border and an attack on Turkish troops guarding the border, which killed one soldier.
