ANKARA (Reuters) - Eight more Kurdish PKK guerrillas have been killed in continuing clashes with Turkish troops in southeast Turkey, bringing the total death toll among the rebels so far to 14, the military General Staff said on Wednesday.

Turkey has stationed up to 100,000 troops in the mainly Kurdish southeast region near its border with Iraq in preparation for possible military strikes against Kurdistan Workers Party (PKK) guerrillas using northern Iraq as a base.

In Wednesday's statement, the General Staff said troops had seized ammunition, equipment and other materials belonging to the rebels, eight of whom had been killed. A Turkish army officer and six guerrillas -- four of them women -- were killed on Tuesday in the first of the clashes, in mountainous Sirnak province near the Iraqi border.

Turkey's military confirmed on December 1 it had conducted an operation inside Iraq against PKK rebels using the region as a base. Military officials say the operation involved special forces and helicopters.

It has said further such cross-border operations are likely under the terms of a parliamentary resolution passed in October.

That resolution encouraged the United States to promise closer cooperation, including intelligence sharing, to help its NATO ally Turkey tackle the PKK, which is listed as a terrorist organization by the United States and the European Union.

Washington is keen to avoid a major, longer-lasting Turkish incursion into northern Iraq, fearing this would destabilize the wider region. As many as 3,000 PKK rebels are believed to be hiding in mainly Kurdish northern Iraq.

Ankara blames the PKK for the deaths of nearly 40,000 people since the group launched its armed campaign for an ethnic homeland in southeast Turkey in 1984.
