The Turkish air strikes hit targets in the Soran district, according to a report on the website of a Kurdish party led by Iraqi President Jalal Talabani. The Patriotic Union of Kurdistan (PUK) website had no details of casualties or damage.
Air strikes in recent weeks have fueled tensions between Turkey and Iraq's semi-autonomous Kurdish region. Between 145 to 160 terrorists were killed in air and artillery strikes on PKK bases in northern Iraq in August, Turkey's armed forces said.
On Saturday, Turkey's southeastern neighbor Iran said its troops had killed or wounded 30 members of the PJAK (Party of Free Life of Kurdistan), an offshoot of the PKK.
The PKK has said it believes Turkey and Iran are coordinating attacks in the region and says it will join forces with the PJAK in response.
The recent wave of cross-border air strikes came after the PKK killed more than 40 Turkish security personnel in July. Two village guards were killed on Sunday, according to security officials. They had been on patrol in the mountainous southeastern province of Hakkari, which borders Iraq.
Two soldiers were killed in a PKK attack on Saturday in the eastern province of Tunceli, where PKK terrorists have been active in recent months. The soldiers were hit while patroling in the rural Geyiksuyu area, state-run Anatolian news agency reported, quoting a statement by the provincial governor's office.
