A group family members of PKK leader Abdullah Ocalan has travelled to İmralı Island to see Öcalan.
Ocalan's sister Fatma Ocalan, niece Dilek Ocalan, uncle Süleyman Arslan and cousin Mehmet Arslan departed from Gemlik on Monday.
The last visit to Öcalan was paid by his brother Mehmet Öcalan on July 1.
Ocalan, 64, is viewed as responsible for the deaths of tens of thousands of people in a 29-year war between the army and the PKK before his capture and conviction in 1999.
Ocalan's Kurdistan Workers Party (PKK) and the Ankara government began peace talks late last year to halt a conflict which has killed 40,000 people and blighted Turkey's mainly Kurdish southeast.
The PKK took up arms against the state in 1984 with the aim of carving out a Kurdish state, but subsequently moderated its goal to regional autonomy.
