A tape of Osama bin Laden and other al Qaeda members purportedly preparing for the Sept. 11 attacks aired on the Arab TV station Al Jazeera Thursday.
The tape is said to have been filmed in Afghanistan.
Al Jazeera said before airing the video that it was new and that it showed bin Laden personally and directly supervising the planning of the attacks.
The video shows bin Laden sitting in a mountainous area surrounded by other men, including Ramzi Bin al Shiba and Abu Hafs al Masri.
Al Shiba has never before been seen in a video with bin Laden.
Two men who have been identified as 9/11 hijackers, Wael al Shahri and Hamza al Ghamedi, are also shown on the video.
They are shown videotaping their wills.
Al Ghamedi talks about the plight of Muslims in Indonesia, Chechnya, Kashmir, Kosovo and Bosnia, and says that the time for jihad has come.
Bin Laden is also seen hugging these men on the tape.
Al Qaeda training techniques are also showcased in the video, as men undergo physical training.
The tape is thought to have been released to coincide with the fifth anniversary of the 9/11 attacks.
