Nearly 400 members of the outlawed Kurdistan Workers Party (PKK) have been killed and hundreds injured in two weeks of Turkish airstrikes on positions in northern Iraq.

Nearly 400 members of the outlawed Kurdistan Workers Party (PKK) have been killed and hundreds injured in two weeks of Turkish airstrikes on positions in northern Iraq, the official Anatolia news agency reported on Sunday.

The report said at least four PKK leaders and 30 female fighters were among the dead.

Turkey last month launched what it called "anti-terror" offensive against the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group in Syria and PKK militants after a wave of attacks inside the country. But so far the Kurdish rebels have borne the brunt of dozens of airstrikes, while just three have been officially recognized as targeting ISIL.

"So far 390 terrorists have been rendered incapable of causing harm and another 400 have been injured, with 150 suffering serious injuries," Anatolia said.

The PKK has meanwhile kept up its attacks on Turkey, killing at least 20 members of the security forces since the start of the latest cycle of violence that has shattered a ceasefire declared in 2013.
