The PKK -- listed as a terrorist organization by Turkey, the U.S. and the EU -- waged a terror campaign against Turkey for more than 30 years and has been responsible for the deaths of nearly 40,000 people, including those of women and children.
More than 1,200 people, including security force personnel and civilians, have lost their lives since the PKK resumed its decades-old armed campaign in July 2015.
