Turkish warplanes killed 13 suspected Kurdistan Workers Party (PKK) militants on Saturday in the southeast province of Diyarbakir, military sources said. According to Reuters, the rebels were spotted by an unmanned aerial vehicle in the Lice region, north of the provincial capital Diyarbakir, the sources said. Warplanes also struck PKK targets in the nearby provinces of Siirt and Hakkari and in some areas of neighbouring northern Iraq where the PKK has bases, the army said.
