Turkey's state-run news agency says the military has carried out air strikes against Kurdish rebel targets across the border in northern Iraq, killing at least 67 militants.

Anadolu Agency, citing unnamed security sources, said Saturday that 14 F-16 and F-4 jets were involved in the March 9 strikes which allegedly destroyed ammunition depots, bunkers and shelters belonging to the Kurdistan Workers' Party, or PKK.

The agency said the offensive targeted five areas in northern Iraq, including the Qandil mountains on the Iraq-Iraq border where the PKK's leadership is based.

Turkey's jets have frequently bombed PKK sites in northern Iraq since July, when a fragile peace process between the government and rebels collapsed.

The PKK, which is fighting for autonomy for Kurds in Turkey's southeast, is listed as a terrorist organization.
