Officials say Kurdish rebels have fired at a police vehicle in southern Turkey, killing a policeman and wounding another, in the latest attack against Turkish security forces.

The governor's office for Mardin province said militants of the Kurdistan Workers' Party, or PKK, opened fire late Saturday at the officers who were on patrol duty.

Militants also fired rockets at a military outpost in the southeastern Mus province. There were no casualties.

Violence in Turkey has flared in recent weeks, shattering an already fragile peace process between the PKK and the government. The rebels launch almost daily attacks at the Turkish security forces while Turkish jets have raided suspected PKK bases in northern Iraq.

The state-run Anadolu Agency claims that more than 260 PKK militants have been killed in the airstrikes.
