At least five Turkish police officers have been killed and as many injured when Kurdistan Workers' Party (PKK) militants carried out three separate attacks in Turkey's southeastern province of Mardin, Press TV reported.
A police chief, identified as Dogan Sakarya, was critically wounded when PKK militants opened fire during a counter-terrorism operation in the Dicle neighborhood of Nusaybin, situated 792 kilometers (492 miles) east of the capital, Ankara, at around 11:40 a.m. (0840 GMT) on Thursday.
The wounded officer later succumbed to his injuries at Nusaybin State Hospital.
Two other policemen, identified as Police Chief Zafer Kurt and Major Ahmet Karaman, lost their lives when PKK militants detonated an improvised explosive device in the same city two hours later.
Additionally, two members of security personnel were killed and five others wounded during a joint operation by gendarmes and special police forces in Nusaybin.
Earlier on Thursday, the Turkish General Staff announced in a statement that Turkish fighter jets had struck PKK positions in the Zap region of Iraq's semi-autonomous Kurdistan region the previous day.
There were no immediate reports of possible casualties and the extent of damage in the Turkish operation.
