Abdullah Ocalan, the imprisoned leader of a Kurdish militant group that has been staging an uprising for years against Turkey, issued an appeal from prison urging the movement he founded to lay down its arms and disband.
The comments by Ocalan, who heads the Kurdistan Workers' Party, or PKK, were read at a press conference in Istanbul by Kurdish lawmakers and leaders who met with Ocalan on Thursday.
His call, under the title "Call for Peace and Democratic Society", came a decade after the last negotiations between Turkey and the PKK broke down and after the possibility of an end to a conflict which has claimed some 40,000 lives since the 1980s was raised.
“I am calling for the surrender of arms and I take historical responsibility for this call,” Ocalan was quoted as saying. “All groups must surrender their weapons and the PKK must be disbanded.”
Ocalan's message is expected to have wide-ranging implications across the Middle East, not least in Syria, where Kurdish forces control significant territory, but also in Iran and Iraq.
The 75-year-old is serving a life sentence in an island prison south of Istanbul after being captured by Turkish special forces in Kenya in 1999.
Ocalan's message will spread through factions of Kurdish armed groups spread across northeastern Syria and northern Iraq with links to the PKK, particularly the US-backed Syrian Democratic Forces (SDF), which fought ISIS militants and remain in control of a swath of territory, including two major cities in eastern Syria.
The group is in talks with the new authority in Damascus following the overthrow of former President Bashar al-Assad, negotiating control over northeastern Syria as well as their future role in a nationwide military force. Ocalan's announcement is likely to put further pressure on and isolate the SDF, who have clashed with Turkish-backed militias in Syria and have long been targeted by Turkish attacks.
