The leader of the July 7th bombings in London was considered such a danger that he was banned from flying to America two years before the attack in London. This is according to a book written by a US Intelligence specialist. MI5 has always denied knowing that Mohammad Sidique Khan was a potential danger, The CIA is alleged to have discovered in 2003 that he was planning attacks on American cities. The claims contradict evidence from Dame Eliza Manningham-Buller, The DG of MI5, to the Parliamentary & Security Committie that Khan had never been listed as a terror threat. The disclosure will add to demands for Tony bLIAR to agree to a full public inquiry into Intelligence lapses before the 7/7 attack.
