Khalid Sheikh Mohammed, said by US authorities to be the no.3 man in Al-Qaeda, has confessed to shooting President John F Kennedy in 1963.
A transcript of his top-secret tribunal at Guantanamo Bay, Cuba, at which the terrorist top-dog also admitted to planning the 9/11 operation and personally beheading US journalist Daniel Pearl, quotes him as saying: "Yeah, why not, I did Kennedy. I was working for a cartel of Texan businessmen, the CIA, the FBI, an organization of anti-Castro Cuban exiles and a secret, underground network of conspiracy book publishers."
The transcript was released by the Pentagon, which is responsible for the Gitmo tribunals at which 'defendants' are not allowed legal representation or witnesses.
The 1,952-page document also reveals Khalid Sheikh Mohammed's key role in the Bali nightclub bombings and attempts at shoe bombings, attacks on airports and plans to kill former US presidents Carter and Clinton.
He added: "I offed Marilyn Monroe, too. Jimmy Hoffa, that was me. I got Jimi Hendrix hooked on drugs. And MySpace was my idea."
He concluded: "I also take full responsibility for the US decision to invade Iraq: it was my fault and no-one else's."
