Umar Farouk Abdulmutallab, a 23-year-old Nigerian, was charged Saturday with the willful attempt to destroy an aircraft, The New York Times reports. Abdulmutallab set off a device attached to his body, the affidavit says, and a preliminary FBI analysis shows the device contained PETN, a high explosive. There was more than enough explosive to set off the bomb, but the make-shift detonator failed to engage, ABC reports. "In addition, FBI agents recovered what appear to be the remnants of the syringe from the vicinity of Abdulmutallab's seat, believed to have been part of the device," the statement said. Abdulmutallab is due in court later Saturday, despite his injuries.
