MI5 could have identified one of the July 7 2005 bombers four months before the attacks on London which killed 52 people, a senior spy admitted at the inquest yesterday.
The MI5 officer said that he could not reveal why security services did not pursue new information due to national security.
MI5 had already observed Mohammed Sidique Khan and Shehzad Tanweer meeting with known terror suspects in 2004. In 2003, Khan was dismissed as a "Jihadi tourist" by MI5 when he travelled to Pakistan for a terrorist training camp. Then in March 2005, MI5 was told that a man from Batley in Yorkshire, named "Saddique", but whose surname was not Khan, had trained in Afghanistan.
MI5 did not follow this lead. "Saddique" was Mohammed Sidique Khan, ringleader of the 7/7 attacks. (© Independent News Service)
