After the 1999 capture of the group's leader, Abdullah Ocalan, the militants are thought to have shifted their bases to areas outside Turkey, and mainly in the mountains of northern Iraq.
Posle hapšenja lidera grupe 1999. godine Abdulaha Odžalana, militanti su, kako se smatra, prebacili svoje baze u oblasti izvan Turske, uglavnom u planinska područja severnog Iraka.
