Turkish warplanes have bombed bases of the outlawed Kurdistan Workers' Party (PKK) in Turkey and northern Iraq, the army said on Tuesday.

"Shelters, caves and arms depots identified as being used by terrorists from the separatist terrorist organisation were destroyed with air bombardments," the military said. The air strikes on Monday targeted PKK bases in the Kurdish-dominated southeastern province of Hakkari near the Iraqi border, as well as several regions in northern Iraq.
