A new Osama bin Laden videotape acquired by CNN from Al-Jazeera features three previously unreleased anti-U.S. rants and harangues by the terrorist leader, excited network sources said Monday. 'One piece goes on for 45 minutes and is entirely about the need to bring down the Great Satan,' CNN spokesman Gil Eckert said. 'In another, shorter piece, he's sitting in a dank cave, cryptically telling some guy off camera about the 'great victory' Allah will enjoy in the very near future.' The eagerly anticipated tape, the first new material from bin Laden in more than two months, hits video stores Tuesday.
