Jailed Kurdistan Workers' Party (PKK) leader Abdullah Ocalan sent a letter to Syrian Arab tribal leaders and sheikhs in regions under Syrian Democratic Forces (SDF) control, including Jazira, Deir Ez-Zor, Raqqa, and Tabqa. The letter, dated September 14th, 2025, expressed Ocalan's support for the "brotherhood and alliance between the Kurdish and Arab peoples, given its historical foundation." In the message, carried by Hawar New Agency (ANHA), Ocalan stated that the tribal leaders "can play an important and historic role in establishing a democratic, secure, unified, and just Syria." He emphasized the importance for "Arabs, Kurds, Syriacs, Assyrians, and all those living on this holy land to take action for this historic fraternity." This communication from Ocalan, who remains imprisoned, aims to foster unity among various ethnic and religious groups within Syria, according to the report from ANHA.
