It was not immediately clear whether any casualties or material damage had been inflicted.
Kurdish sources denied however earlier reports that planes had bombed a number of areas in northern Iraq, but confirmed that Turkish warplanes had patrolled border areas.

In mid-October, Turkey's parliament sanctioned cross-border military operations against Kurdistan Workers' Party (PKK) separatists following an earlier government request and despite opposition from Washington and Baghdad.
Turkey's Defense Ministry had previously confirmed it had carried out several "limited operations" against the outlawed PKK in December.
The PKK, labeled by the U.S., NATO and the EU as a terrorist organization, has been fighting for autonomy status in southeast Turkey for nearly 25 years. The conflict has so far claimed about 40,000 lives.
