(CNN) -- Turkish fighter jets targeted suspected Kurdish militants in overnight airstrikes along the country's border with Iraq, the military said Sunday.
The airstrikes targeted a shelter and a cave believed to be used by militants in Zap and Hakurk areas of northern Iraq, the military said.
There were no immediate reports of casualties.
Fighters from the Kurdistan Workers Party have been waging a guerrilla war against the Turkish state since the early 1980s. More than 30,000 people, most of them ethnic Kurds, have been killed in the conflict.
The Kurds are Turkey's largest ethnic minority, and for decades, they have been targeted by discriminatory state policies that banned Kurdish language and education.
