Turkey has been carrying out operations against the PKK at home and abroad since late July, amid a spike in attacks targeting security officers.
The renewal of fighting between the PKK and Turkish security forces marked the end of the fragile two-and-a-half year lull to fighting -- dubbed the “solution process” -- aimed at resolving the 30-year conflict.
Founded in the late 1978, PKK is considered a terrorist organization by Turkey, the EU and the U.S.
