Al-Jazeera television tonight screened what it called previously unshown footage in which al-Qaeda chief Osama bin Laden is seen meeting with some of the 9/11 hijackers.
The station did not say how it obtained the video, which was produced by As-Sahab, al-Qaeda's media branch.
The video showed bin Laden sitting with his former lieutenant Mohammed Atef and Ramzi Binalshibh, another suspected planner of the 9/11 suicide hijackings.
Atef, also known as Abu Hafs al-Masri, was killed by a US airstrike in Afghanistan in 2001.
Binalshibh was captured four years ago in Pakistan and is currently in US custody, and this week US President George Bush announced plans to put him on military trial.
In the video, Bin Laden was wearing a dark robe and white head gear walking outdoors in a mountainous area. He smiled as he received several of what the tape said were September 11 hijackers.
