July 23, 2005: Head 7/7 London Bomber Said to Have Been Trained in Explosives by Al-Qaeda Operative

The Telegraph reports that Pakistani officials believe Mohammad Sidique Khan, the lead suicide bomber in the 7/7 London bombings (see July 7, 2005), spent much of his time during his trips to Pakistan with an al-Qaeda operative named Mohammed Yasin, a.k.a. Ustad Osama. Yasin is said to be an explosives specialist also linked to the Pakistani militant group Harkat ul-Jihad al-Islami (which in turn is related to the Harkat ul-Mujahedeen group). He is based in the training camps near the Afghan-Pakistani frontier and is reputed to be an expert at manufacturing “suicide jackets.” Yasin was included on a Pakistani government list of 70 “most wanted” terrorists in December 2003.
