A video threatening America was posted online by an al-Qaeda activist four days before the failed attempt to blow up the plane in Detroit.
It appeared on extremist website on December 21st. The sites have identified the man speaking as Mohammed al-Kalwi, an al-Qaeda member in Yemen.
In the video, al-Kalwi says ‘we are carrying a bomb’. However, there is no clear evidence that he knew of the coming botched attempt to blow up a plane on Christmas Day.
It has attracted attention because it is thought that the bomb plot may have originated in Yemen.
