Russia said there was little hope of finding any more people alive on Monday after an overloaded tourist boat sank in the Volga River, killing 128 people in Russia's worst river accident in three decades.

On Sunday, the boat carrying more than 200 vacationers on a cruise of the Volga and Volga Reservoir capsized when it was hit by a side-length wave during a rain storm.

Russian national flags were half flutter on Sunday as a mourning for the died victims of the boat disaster.
