DETROIT, Dec. 29 (UPI) -- The Nigerian accused of an attempted suicide bombing of a U.S. airliner Christmas Day said online he was "lonely" and had "never found a true Muslim friend." The postings were uncovered in a review by The Washington Post. Umar Farouk Abdulmutallab, 23, was released from a Michigan hospital Sunday, officials said. He was charged with attempting to ignite an incendiary device aboard a Friday flight from the Netherlands to Detroit.
