Al Qaeda: We Did It

This settles the question of whether Umar Farouk Abdulmutallab, the man who allegedly tried to bomb a Detroit-bound plane, was part of a larger terrorist network: Al Qaeda in the Arabian Peninsula has claimed responsibility for the attempted bombing, saying that it was a response to a U.S. attack on the group in Yemen. According to ABC News, Abdulmutallab warned in his interrogation that there are more al Qaeda-trained men in Yemen preparing to blow up American planes. Abdulmutallab told investigators that he trained for a month with the terrorist group in Yemen, where he was given the underwear with 80 grams of explosives sewed in. Al Qaeda in the Arabian Peninsula claims on its Web site to have manufactured Abdulmutallab's explosives.
