Turkey's military says 15 Kurdish rebels have been killed in Turkish attacks on suspected rebel targets in northern Iraq.

The military said Saturday the rebels - from the outlawed Kurdistan Workers Party (PKK) - were killed Thursday in artillery fire aimed at stopping the group from attacking Turkish targets.

A military statement said Turkish warplanes followed up the attack with airstrikes in northern Iraq Friday, but it was unclear if there were casualties.

Turkey accuses PKK militants of using suspected strongholds in northern Iraq to launch attacks in Turkey.

The PKK has been fighting for Kurdish autonomy in Turkey's mainly Kurdish southeast for nearly 25 years.  The violence has killed more than 30,000 people.

Turkey, the United States and other nations have designated the PKK a terrorist group.
