DIYARBAKIR, Turkey  - Turkish troops have killed 16 Kurdish guerrillas in an operation in southeastern Turkey targeting militants who launched a bomb attack on a military convoy that killed five soldiers, the local governor’s office said on Thursday. The clashes are part of a growing cycle of violence in the remote, mountainous province of Hakkari bordering Iraq and Iran - a development which Turkish officials and analysts are linking to the deepening conflict in Syria. The army sent in troop reinforcements and helicopter gunships after Kurdistan Workers Party (PKK) rebels detonated remote-controlled bombs in the attack on the army convoy in Hakkari’s Semdinli district on Wednesday.
