The Turkish military on Sunday carried out airstrikes on positions held by the Kurdistan Workers' Party (PKK) in northern Iraq, state-run Anadolu news agency reported.
Security forces said several PKK hideouts were destroyed in Iraq's mountainous Kandil region, where the PKK has its headquarters.
Turkish F-16 and F-4 2020 warplanes also hit the areas of Medina, Zap and Gara, Anadolu reported, destroying bunkers and ammunition depots.
Meanwhile, Anadolu reported that Turkey also fired across the border in Syria, killing 55 Islamic State militants, and destroying three rocket launchers and three vehicles.
Islamic State controls territory along Turkey's border and the southern Turkish town of Kilis has been hit by rocket attacks on a near-daily basis.
