Turkish forces have killed 771 militants of the Kurdistan Workers Party (PKK) in northern Iraq and southeastern Turkey over the last four weeks, the state news agency Anatolia said Friday. The agency said among those killed were 430 rebels who died in air raids in PKK camps in Iraq. Another 260 were killed in ground operations in southeastern Turkey, Anatolia said, quoting military intelligence sources. The offensive was launched after 33 pro-Kurdish activists were killed on July 20 in a suicide bombing on the Syrian border blamed on Islamic State jihadists. On July 24 Ankara launched its first airstrikes against IS in Syria and then also began attacking targets of the PKK in northern Iraq, in a dual war on terror. Dozens of airstrikes have been carried out, but only three have officially been targeted at IS. The PKK, for its part, has been blamed for attacks that have killed around 50 Turkish soldiers. Eight were killed on Wednesday in a remote-controlled roadside bomb in the southeastern province of Siirt.
