FILE - In this Saturday, Oct. 26, 2002 file photo, a bus with unidentified unconscious people, who are claimed to be liberated hostages, leaves the scene near the theater, which was seized by Chechen rebels, in Moscow, Russia. This week Russia marked the 10th anniversary of a Chechen rebel hostage-taking raid on a Moscow theater. The attackers took about 800 people hostage, and 129 of the captives died, nearly all from the gas Russian special forces used to knock the hostage-takers out before storming the theater.
