Al-Qaeda on Tuesday released a new 106-minute long video predicting President Barack Obama's downfall at the hands of the Muslim world. The Arabic-language video, entitled "The West and the Dark Tunnel," is part of series of messages by the organization marking the eighth anniversary of the Sept. 11 attacks. Bin Laden released a short message of his own on Sept. 14. Like similar long messages on previous anniversaries, it featured testimony from several leading al-Qaeda figures intercut with news footage from the past year.
