A soldier was killed and another was injured in a PKK terror attack in southeastern Turkey on Wednesday night, a security source said.

The soldiers were injured when a homemade bomb exploded during an anti-terror operation in Sur district of southeastern Diyarbakır province. The unnamed source, who spoke on condition of anonymity, said one soldier later succumbed to his wounds at Diyarbakır Military Hospital.

The Turkish government has intensified its counterterror operations following the recent attacks carried out by the PKK, which is recognized as a terrorist organization by the U.S., the EU and Turkey.

Formed in 1978, the terrorist group has been fighting the Turkish government for an independent state until the early 2000's. The group then shifted its goal to autonomy in predominately Kurdish inhabited regions of Turkey.
