February 2005: British Intelligence Warned 7/7 Bomber Has Traveled to Afghanistan, but Apparently Fails to Learn His Real Name

British intelligence receives a report naming two people with extremist views who had traveled to Afghanistan. Apparently only their aliases are given, because the British intelligence agency MI5 tries and fails to discover who they are. Only after the 7/7 London bombings (see July 7, 2005) does it learn that one of them was Mohammad Sidique Khan, the head 7/7 suicide bomber. [Observer, 1/14/2007] Khan traveled to training camps in Pakistan several times, most recently from November 2004 to February 2005. He returned to Britain on the same flight as Shehzad Tanweer, another one of the 7/7 suicide bombers (see November 18, 2004-February 8, 2005).
