Turkish officials say Kurdish separatist militants have killed four soldiers in an overnight ambush in the eastern part of Turkey.
Authorities say militants of the Kurdistan Workers Party, armed with rocket launchers, attacked a local commando unit on patrol in Tunceli province in a pre-dawn raid on Sunday. One Turkish soldier was wounded.
Fighting between the government and the Kurdish rebels subsided in 1999 after the rebels declared a cease-fire with Ankara. But rebels called off the truce last June, saying they were not satisfied with the pace of promised Turkish reforms.
The Kurdistan Workers Party has been fighting for an ethnic homeland in southeastern Turkey for more than two decades. More than 30,000 people have died since their revolt began in 1984.
