The outlawed Kurdistan Workers Party (PKK) has claimed responsibility for the killing of an official from Turkey's ruling Justice and Development Party (AKP).
In a statement issued on October 11, the PKK said it was behind the killing, the second such incident in recent days.
Deryan Aktert, who headed the AKP branch in Diyarbakir's Dicle district, was shot and killed on October 10, the provincial governor's office said.
His death marked the second attack targeting ruling party officials within 24 hours, after the killing of Aydin Mustu on October 9 in the eastern province of Van.
The PKK, listed as a terror group by Turkey and its Western allies, has waged a bloody insurgency against the Turkish state since 1984.
The group has resumed attacks on Turkish security forces after the collapse of a fragile truce in 2015.
