At least 29 terrorists were killed in an counter-terrorism operation in Turkey’s eastern province of Agri, the governor's office said on Friday.

Axar.az reports citing Anadolu.

Gendarmerie forces conducted an operation after three trucks were set fire by PKK terrorists on a highway, the office said in a statement.

Three Turkish soldiers and one village guard were martyred in the clash, the statement said.

The PKK -- listed as a terrorist organization by Turkey, the U.S. and EU -- resumed its armed campaign against Turkey in July 2015.

Since then, it has been responsible for the deaths of around 1,200 people, including women and children.
