Two Turkish security personnel died in PKK attacks in the southeastern provinces of Sirnak and Diyarbakir late on Saturday.
Murat Sevim, a village guard in Sirnak's Ismetpasa neighborhood, was severely wounded when he was attacked by PKK terrorists near his house.
He died later at Sirnak State Hospital.
Earlier in the day, one Turkish soldier died in the Sur district of Diyarbakir province during a counter-terrorism operation against the PKK.
He succumbed to injuries sustained in the attack which happened while troops were filling ditches, removing barricades and defusing explosives planted by the PKK.
Four PKK terrorists were also killed in the same operation in Sur, according to a statement from the Turkish General Staff.
Sixteen other terrorists were killed during anti-terror operations in Cizre and Sur on Saturday.
The two southeastern districts have been among areas that have been the focus of counter-terror operations and military curfews since early December 2015.
More than 600 PKK terrorists have been killed in the two districts since counter-terror operations began, according to a Turkish General Staff statement issued Saturday.
PKK terror attacks have killed more than 200 security officers in Turkey since the group’s umbrella organisation, KCK, unilaterally ended a two-and-a-half-year-long ceasefire with the government on July 11 and threatened Turkey with attacks.
