The man behind al-Qaeda’s new online magazine, Inspire, is likely a US citizen. Authorities suspect 23-year-old North Carolina resident Samir Khan of being the magazine’s “driving force,” a senior law enforcement official tells CNN. Khan, who has long distributed translations of al-Qaeda propaganda on his “Jihad Recollections” blog, traveled to Yemen in October on a round-trip ticket, but hasn’t returned. Khan was originally born in Saudi Arabia, but his family moved to New York when he was 7, and later to the Charlotte area. (More al-Qaeda stories.)
