At least two Turkish soldiers have been killed in a roadside bomb explosion that targeted their military vehicle in Turkey’s southeastern and Kurdish-populated province of Diyarbakir.
Security sources said on Tuesday that militants of the Kurdistan Workers' Party (PKK) detonated an improvised explosive device as the vehicle was passing a road through the troubled province.
Turkish security forces have launched a ground and air operation to hunt down the militants across the region.
Separately, three PKK militants were killed in the southeastern province of Tunceli after being identified by a drone.
Turkey has declared the PKK a terrorist organization and has banned it. The militant group has been seeking an autonomous Kurdish region since 1984.
A shaky ceasefire between the PKK and the Turkish government collapsed in July 2015. Attacks on Turkish security forces have soared ever since.
Over the past few months, Turkish ground and air forces have been carrying out operations against the PKK positions in the country’s southeastern border region as well as in northern Iraq and neighboring Syria.
More than 40,000 people have been killed during the three-decade conflict between Turkey and the autonomy-seeking militant group.
