Turkey's state-run Anatolia news agency says autonomy-seeking Kurdish rebels have killed one soldier and wounded three others in an ambush in eastern Turkey.

Anatolia said Monday the overnight attack occurred near the town of Saray, in Van province bordering Iran. It says two of the wounded soldiers are in serious condition.

The rebels of the Kurdistan Worker's Party, or PKK, are waging a campaign for autonomy in southeast Turkey. The conflict has killed tens of thousands of people since 1984.

The group's imprisoned leader, Abdullah Ocalan, had warned of increased violence unless the government puts an end to the fighting with the rebels.
