Members of the Kurdish security force in the autonomous north of Iraq said the raids, which began around 10:00 pm (2000 GMT) Sunday, continued overnight in and around Hakurk, a prominent PKK stronghold some 20 kilometres (12 miles) from the Turkish frontier.
Billows of smoke could be seen miles away, they said.
The Firat news agency, considered to be a PKK mouthpiece, said on its Internet site that warplanes took off from the military air base in Diyarbakir, the main city in Turkey's southeast, late Sunday.
The raids came after fighting intensified between Turkish troops and PKK militants around Hakurk.
Turkish troops crossed into northern Iraq Thursday evening in the largest cross-border offensive in years against PKK hideouts in the region, bombing PKK positions and fighting the militants on the ground.
The Turkish army said Sunday that it killed 112 PKK militants and lost 15 soldiers since the beginning of the incursion.
