A cruise ship carrying 182 people sank in Russia's Volga River on Sunday, leaving at least one person dead and large numbers missing, emergency officials said.
The ship, the Bulgaria, sank about 2 p.m. (6 a.m. ET) with 125 passengers and a crew of 57 aboard, Russia's Emergency Situations Ministry reported. A total of 84 people had been rescued Sunday evening, the ministry said.
The state-run news agency RIA Novosti reported that police have opened a criminal investigation into allegations of safety violations aboard the vessel.
One woman was confirmed dead and 88 remained missing, RIA Novosti said.
The agency said double-deck cruise ship went down near the village of Syukeyevo, in the Russian republic of Tatarstan. Russian officials said two ships and two helicopters responded to the incident, about 50 miles south of the city of Kazan -- about 450 miles east of Moscow.
In all, 22 rescue units including 80 people were involved in the operation, RIA Novosti reported.
