The PKK terrorist group on Wednesday attacked road workers in southeastern Turkey’s Hakkari province, killing one and wounding another two.

According to a statement from the governorate, PKK terrorists attacked heavy construction equipment in Hakkari’s Derecik district close to the Iraqi border with rockets and long-barreled weapons. An investigation into the attack has been launched, the statement added.

"Three workers who devotedly labored to earn a living for their families were barbarously murdered by the PKK terrorist group," deputy foreign minister Yavuz Selim Kıran stated on Thursday. "Our fight against terrorist organizations will continue until the end," he wrote on Twitter.

In its more than 40-year terror campaign against Turkey, the PKK – listed as a terrorist organization by Turkey, the U.S. and the European Union – has been responsible for the deaths of 40,000 people, including women and children.
