The PKK confirmed the attack and said one of its members was wounded.

The bombing took place at around 10:15 pm (1915 GMT) Thursday in Zarawah and Senkser districts near the Qandil mountains along the border with Turkey and Iran, said Azad Wasso, local adminstrator for the Zarwah district.

"Last night, Turkish aircraft attacked several areas in Zarawah and Senkser districts," he said, adding the bombings continued till midnight, but caused no casualties.

PKK spokesman Ahmed Danis said "one of our members was wounded in the attack. We knew they were planning to attack."

Since last October, Ankara has carried out several air strikes and a week-long ground incursion against PKK rebel targets, using intelligence passed on by Turkey's close ally, the United States.

The army has described the raids as successful and said they inflicted massive damage and casualties on PKK militants.

The PKK -- considered a terrorist group by Turkey, the United States and the European Union -- has been fighting for a separate state in the mainly Kurdish southeast and east of Turkey since 1984.

The conflict has claimed some 44,000 lives.

Turkey claims that thousands of PKK militants are holed up in rear bases in northern Iraq from where they stage cross-border attacks on Turkish targets.
