Two police officers were killed in a car bomb explosion in south-eastern Turkey on Friday, the state-run Anadolu news agency said.
The attack in the town of Nusaybin targetted a police station and a nearby residence for Turkish security forces, the report said.
Several other people were injured in the blast, which tore a deep crater in the road.
Nusaybin lies on the border with Syria and is stronghold of the Kurdistan Workers' Party (PKK).
Violence between the state and the PKK, which the government deems a terrorist group, erupted last year, after a two-year ceasefire collapsed as peace talks stalled.
The army has been waging a campaign against the militants in southern Turkey since December. Many hundreds of people have been killed, mostly PKK fighters, but also civilians and members of the security forces.
