ANKARA — Turkish warplanes struck 64 Kurdistan Workers Party (PKK) targets in overnight raids on northern Iraq, dropping 80 bombs, the Turkish media reported Friday. At least 60 PKK militants were killed in the strikes, carried out by 21 Turkish F-16 and F-4 warplanes, the state-run Anatolia news agency reported, quoting security sources. The toll could not be verified independently. The strikes, which ran from late Thursday to dawn Friday, are the latest in a relentless air campaign aimed at crippling the PKK, which has staged a string of attacks in Turkey in recent weeks. In Diyarbakir, the largest city in the mainly Kurdish southeast, suspected PKK militants opened fire on a restauranton Friday morning, wounding three police officers and one civilian, security sources said. One of the officers was seriously hurt. Further south, a round-the-clock curfew in the town of Cizre entered its eighth day. Pro-Kurdish politicians say 21 civilians have been killed and a humanitarian crisis has unfolded since authorities imposed the curfew to combat PKK fighters. — Agencies
