An attack at a police checkpoint in Eastern Turkish city of Tunceli allegedly carried out by Kurdistan Workers` Party (PKK) left one police officer dead and two seriously injured, local media reported Sunday.

Those wounded were transferred to Tunceli State Hospital and then to Firat University Hospital, Anadolu news agency reported.

Tensions between Ankara and the Kurds escalated in July 2015 when a ceasefire between Turkey and the PKK collapsed over a series of terror attacks allegedly committed by the PKK members.

Turkish authorities have imposed several round-the-clock curfews in Kurdish-populated towns in country`s southeast, preventing civilians from fleeing the regions where the military operations are taking place.
