The PKK - listed as a terrorist organization also by the U.S., and the EU - resumed its armed campaign against the Turkish state in July 2015.
Since then, nearly 600 security personnel, including troops, police officers, and village guards, have been martyred, and more than 7,700 PKK terrorists killed in operations across Turkey and northern Iraq
