The evidence files inclue testimony from many witnesses whose real identities are being kept secret due to security concerns and legal necessity. According to a witness using the alias Deniz, PKK leader Abdullah Öcalan and other higher-ups in the terrorist group knew that a coup d'état was in the works ahead of Sept. 12, 1980, when Turkey's bloodiest military intervention occurred. According to Deniz's testimony, Ergenekon suspects Professor Yalçın Küçük and Doğu Perinçek, who is the leader of the Workers' Party (İP), had close ties with Öcalan.
In his testimony, Deniz states that Perinçek visited the PKK's Helve base in Syria, near the Bekaa Valley, between the years 1986 and 1987. Perinçek was welcomed with a military ceremony at the camp. Deniz continues: “Öcalan never had more than one meal with any of his guests. He ate every meal with Perinçek. Öcalan would normally be superficially nice to his guests, telling them nice things but talking behind their backs, calling them collaborators or agents. However, he always spoke highly of Perinçek. After Perinçek's interview with Öcalan was published, Perinçek became the second leader of the organization. The interview itself became the Bible of the militants.”
Küçük led PKK to armed attacks
Secret witness Deniz claims that Küçük also visited the PKK's Damascus base many times between 1993 and 1996. The witness said: “Yalçın Küçük's role in the PKK was to direct Abdullah Öcalan to stage armed attacks. Öcalan always told Küçük, ‘Every word you say sparks flames in my head.' Öcalan always did situational assessments with Küçük. Küçük was just like his brain.”
