Turkish warplanes have attacked targets of the separatist Kurdistan Workers Party in northern Iraq.
They hit bases, anti-aircraft defenses and rebel shelters in the Kandil and Zap regions.
Wednesday's military strikes came hours after a deadly assault by PKK rebels killed eight Turkish soldiers in Hakkari province near the Turkey-Iraq border.
Turkish and Kurdish media reports, citing unidentified military sources, reported the air strikes. If officially confirmed, the raids would be Turkey's first cross border offensive in a year.
