At least one other civilian was also injured in the attack.
Two PKK terrorists had first opened fire on the car of Kozluk mayor, which was being driven by one of his relatives. However, the gun shots ended up killing a 22-year-old music teacher and injuring another civilian.
Later security forces intercepted one of the two terrorists at a gendarmerie station near the entrance to Bekirhan in Kozluk; however, the terrorist blew up the car when told to stop, wounding two soldiers and a civilian.
An operation is underway to capture the other terrorist.
Separately, two soldiers were martyred and three others injured when the PKK terror group attacked a military base in southeastern Sirnak province on Friday, a military source, who asked not to be named due to restrictions on talking to the media, said.
The PKK -- listed as a terrorist organization by Turkey, the U.S. and EU -- resumed its armed campaign against Turkey in July 2015. Since then, it has been responsible for the deaths of around 1,200 people, including women and children.
