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.
