Retrieval Effort For Sunken Moscow Riverboat
Russia's RIA Novosti news agency quoted Yury Bessedin, deputy director of the Moscow branch of the Emergency Situations Ministry, as saying that the accident may have been caused by an infraction of river navigation rules.
The sinking came just three weeks after Russia's worst post-Soviet river-boat accident -- when 122 people died aboard a tourist boat that sank on July 10 on the Volga River in the central Russian republic of Tatarstan.
