The Turkish military says its warplanes attacked a group of Kurdish rebels in northern Iraq as they tried to sneak across the border into Turkey.

A military statement issued Wednesday said the rebels were "rendered ineffective" by the raid on Tuesday.  The military did not provide casualty figures.

A spokesman for the rebel Kurdistan Worker's Party (PKK), said Turkish airplanes bombed some areas of the Zagros Mountains bordering Turkey and Iraq, but he added there were no reports of any casualties.

The Turkish military statement also said troops killed at least one militant Tuesday in clashes with PKK rebels in two areas of southeast Turkey.  Various weapons and bomb-making equipment were seized from the rebels.

Turkey accuses the PKK of using strongholds in northern Iraq to launch attacks.  The military has conducted several airstrikes and at least one ground incursion into Iraq against the rebels this year.

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.
