The magazine – called "Inspire" – appeared last week. Running to nearly 70 pages, it included articles on bomb-making and encrypting electronic messages, as well as an interview with the fugitive Yemeni-American cleric, Anwar al Awlaki.
The source has identified the driving force behind "Inspire" as 23-year old Samir Khan, who previously lived in North Carolina and was involved in radical Islamist blogs, including one he ran called "Jihad Recollections." The source says Khan traveled to Yemen on a return ticket but has not come back to the United States.
Before moving to North Carolina, Khan lived in the New York area. U.S. law enforcement officials say he attended meetings of the Islamic Thinkers Society, but was not a central figure in the group. The Islamic Thinkers Society says its mission is to achieve the ideal Islamic society. On its website it says: "Our struggle is always intellectual & political non-violent means."
Khan's online name was inshaAllhashaheed (Arabic for "God willing a martyr.") On his various blogs he distributed English translations of Al Qaeda propaganda and links to videos produced by Iraqi insurgent groups and others. In a profile in 2007, the New York Times described him as serves as "a kind of Western relay station for the multimedia productions of violent Islamic groups."
Khan was born in Saudi Arabia, and moved to Queens, New York, with his family when he was seven. The family later moved to Charlotte, North Carolina.
