New footage has been released which appears to show the man charged with trying to blow up a plane on Christmas Day training with al Qaeda in Yemen.
The video seems to show Umar Farouk Abdulmutallab and other men firing weapons at targets, including the Union Flag and the UN flag.
According to ABC News, which obtained and broadcast the tape, the video was produced by al Qaeda in the Arabian Peninsula (Aqap) - a group formed in January 2009.
It was not clear where and when the video was made or whether it was genuine.
Abdulmutallab is charged with attempting to bring down a Detroit-bound jet by detonating explosives hidden in his underwear.
He has pleaded not guilty to the charges, but is said to be co-operating with US intelligence agencies interviewing him.
The 23-year-old has allegedly told investigators that Aqap fighters trained him in Yemen, equipped him with a powerful explosive device and told him what to do.
He also warned there were others like him ready to strike, according to US officials.
SkyNewsDidn't Lord Zero tell us that this guy acted alone and was a lone wolf, with no co-conspirators?
