Two sergeants were killed on Thursday by PKK terrorists in Silvan District of Diyarbakir Province in Turkey's southeast.
According to security sources, the sergeants - Tolga Topcuoglu and Sinan Ucan - were on their way to meet with their troops when PKK terrorists attacked them with gunfire.
A comprehensive investigation was launched immediately following the terror attack to find the attackers.
The PKK is recognised as a terrorist organisation by Turkey as well as NATO, the US and EU.
The PKK began renewed terror attacks in Turkey after its umbrella organisation, the KCK, unilaterally ended a two-year-long ceasefire with the government on July 11.
Since then, terror attacks by the group have claimed the lives of at least 131 security officers and 30 civilians.
