Turkish warplanes destroyed targets belonging to the militant Kurdistan Workers Party (PKK) in southeast Turkey, the military said on Wednesday.

The raids came after a soldier was killed and five people were wounded in a car bomb attack carried out by Kurdish militants near a military installation in southeast Turkey overnight.

PKK militants were behind the attack at 00:50 am (2150 GMT) near a gendarmerie base in the Derik district of Mardin province, near the Syrian border, the military said.

Four of the wounded were soldiers, it added.

Turkey’s state-run Anadolu news agency said six people were injured in the attack.

The PKK, designated a terrorist group by Turkey and its Western allies, began a separatist insurgency in 1984 and more than 40,000 people have been killed in the conflict.

The conflict reignited last summer, putting an end to a 2½-year peace process and leaving thousands of people dead.

At least 42 PKK fighters were killed in air strikes in northern Iraq and clashes in southeast Turkey on Monday and Tuesday and three soldiers died, the military said on Tuesday.
