NTV said at least 30 F-16 Fighting Falcon multirole fighters had hit the Qandil Mountains, believed to harbor the main bases of the separatist Kurdistan Workers Party (PKK), for more than an hour. Other media reports said the strikes lasted three hours.
Turkey's General Staff has not confirmed the bombings. No casualties have been reported.
The Turkish Air Force last carried out strikes on northern Iraq April 25-26.
The PKK has been fighting for an autonomous ethnic Kurd state in southeast Turkey for nearly 25 years, killing more than 40,000 people in that period. The PKK uses northern Iraq to stage attacks on Turkey.
In February, the Turkish army held a large-scale cross border operation against the PKK, considered a terrorist organization by the U.S. and EU, killing, according to official data, 240 militants.
