PKK founding member Mustafa Karasu wrote in 2017 (just to make decades of policy totally clear):
Since the emergence of the PKK, we have been against Zionism. We compared the genocide of the Kurds in Turkey with Israeli Zionism and the apartheid regime of South Africa. Since its founding, the PKK has fought side by side with the Palestinians. In 1982, 13 of our cadres fell in the fight against the occupation of Lebanon by Israel. The Israeli state also participated in the international conspiracy against Abdullah Öcalan, and murdered four of our comrades in Berlin. No doubt, we will never forget the support the Palestinians gave to the Kurdish people in the 1980s.
Our attitude towards Zionism has always been ideological. Until today, we stand on the side of the Palestinians and all those who are fighting for a democratic solution in the region.
