People take part in the funeral ceremony for seamen who got killed during an accident on Russia's Nerpa nuclear submarine in Bolshoi Kamen, 35 km (22 miles) east of Vladivostok, November 13, 2008. Russian prosecutors said on Thursday they had opened a criminal case against a sailor suspected of triggering the accident on the Russian nuclear submarine that killed 20 people at the weekend. Prosecutors said the accident, which occurred during sea trials of the Nerpa nuclear submarine on Saturday in the Sea of Japan, was caused when the fire extinguishing system was turned on, releasing freon gas that asphyxiated the victims.
