(AP) - President Obama laid blame today on an al-Qaeda affiliate for the Christmas Day terrorist attack on a Detroit-bound airliner. In his most direct public language to date, the president described the path through Yemen of 23-year-old Umar Farouk Abdulmutallab, the Nigerian accused of trying to destroy Northwest Flight 253. "We know that he traveled to Yemen, a country grappling with crushing poverty and deadly insurgencies. It appears that he joined an affiliate of al-Qaeda, and that this group—al-Qaeda in the Arabian Peninsula—trained him, equipped him with those explosives and directed him to attack that plane headed for America," the president said in his weekly radio address.
