The hunger strike, demanding an end to Ocalan's isolation, is stretching into its third month and medics have warned that some prisoners could soon die. The action has presented a growing challenge for and risked fuelling tension in Turkey's mainly Kurdish southeast.
"Today I went to see my brother Abdullah Ocalan face-to-face in Imrali prison," the statement said.
"He wants me to share immediately with the public his call about the hunger strikes ... This action has achieved its goal. Without any hesitation, they should end the hunger strike."
Ocalan, the leader of the Kurdistan Workers Party (PKK) terror group, which has been fighting for Kurdish autonomy for almost three decades, has been imprisoned on the small island of Imrali in the Marmara Sea since his capture in 1999.
He has significant support among Kurds but is widely reviled by Turks who hold him responsible for the deaths of over 40,000 people since the PKK - designated a terrorist group by Turkey, the United States and the European Union - took up arms.
