A Nigerian man has been indicted on additional charges, including terrorism, for a botched attempt to blow up a Northwest Airlines flight from Amsterdam to Detroit last Christmas Day.
A federal grand jury in Detroit on Wednesday issued a superseding indictment accusing Umar Farouk Abdulmutallab with conspiracy to commit an act of terrorism and possession of a destructive device.
The indictment says Abdulmutallab and others conspired to kill nearly 300 people on Flight 253.
Abdulmutallab is representing himself in the case. Standby counsel Anthony Chambers said he had no comment on the superseding indictment.
