U.S. investigators were reviewing a videotape of the accused underwear bomber Umar Farouk Abdulmutallab apparently receiving weapons training before he allegedly tried to blow up a U.S. airliner, Attorney General Eric Holder said on Tuesday.
ABC News broadcast the videotape on Monday in which Abdulmutallab, 23, originally from Nigeria, made an apparent martyrdom statement in Arabic and also appears holding a machine gun at a desert training camp. ABC News said the video was produced by al-Qaida in Yemen.
"We'll be looking at all of the information, all the evidence that is uncovered and going through with him much of this information so that we can glean actionable intelligence," Holder told reporters in response to a question about the tape.
Holder said he had seen the videotape, which shows others at the training camp, but some of them had their faces blurred or covered. It also shows bullets being fired into a flag with "UN" written on it and another one with a Jewish star on it.
In the video, Abdulmutallab says Muslims in the Arabian Peninsula "have the right to wage Jihad because the enemy is in your land." He is shown reading from the Quran and saying, "God said those who punish you must be punished."
On Christmas Day last year, Abdulmutallab tried but failed to blow up a U.S. commercial flight from Amsterdam to Detroit with a device hidden in his underwear, U.S. officials said.
He was arrested and has been cooperating with investigators, discussing his contacts in Yemen and providing intelligence in multiple terrorism investigations, according to U.S. officials.
He has previously told investigators he was trained by militants in Yemen affiliated with al-Qaida that they gave him the bomb.
