In July 2001, Mohammad Sidique Khan, the lead suicide bomber in the 7/7 London bombings (see July 7, 2005), trains in an al-Qaeda camp in Afghanistan (see July 2001). Presumably later in the year, he is sent on a mission to Southeast Asia, where he meets al-Qaeda leader Hambali. Making a total of two trips to the region, Khan is assigned to assess for al-Qaeda how much funding its Southeast Asian affiliate Jemaah Islamiyah (JI) needs. This is according to a militant who will later be jailed in Malaysia. This militant says he takes Khan to meet Nasir Abbas, a JI leader, who then takes Khan to a JI training camp on the southern Philippine island of Mindanao, where Khan learns bomb-making skills. Abbas will later corroborate the account after being captured in Indonesia. [Time, 9/26/2005; Manila Times, 10/27/2005] Abbas will claim that while Khan is in the Philippines, he meets Azhari Husin, a chief bomb-maker for JI who is linked to most of JI’s major bombings. While Husin is Indonesian, he studied in Reading, England, and received a doctorate in engineering there in 1990. [Evening Standard, 10/26/2005] Abbas, the brother-in-law of Ali Gufron, another JI leader and one of the masterminds of the 2002 Bali bombings, will be captured in April 2003. He will be able to avoid a jail term by fully cooperating with the authorities, but it is unknown if his information about Khan is shared with British intelligence before the 7/7 bombings.
