Another civilian was also injured in the incident and immediately taken to hospital.
Anti-terror operations against the PKK are still ongoing in the region, while a curfew also has been in place to ensure the safety of civilians.
The PKK - considered to be a terrorist organisation by Turkey, the US and EU - resumed its 30-year armed campaign against the Turkish state in late July.
Since then, more than 200 members of the Turkish security forces have died while many civilians have been killed in PKK attacks.
Turkish security forces have stepped up operations against the PKK in southeastern towns and cities and 240 terrorists have been killed since Dec.15, the military said on Friday.
