The Arab TV station, Al-Jazeera, has aired a videotape that shows al-Qaeda leader Osama bin Laden meeting what the channel said were the perpetrators of the 11 September attacks.
The broadcast comes just days before the fifth anniversary of the strikes.
The video, which shows bin Laden in one scene greeting a fighter against the backdrop of a mountain, also contained parts of taped 'wills' of two of the hijackers.
The television station said the tape documented the 'daily life' of al-Qaeda operatives as they trained and prepared for the attacks in the mountains of Afghanistan.
