DHAKA: At least 54 sailors were so far confirmed dead as a Russian trawler has sunk off the Kamchatka peninsula of the country.

Some 63 people have been rescued, many suffering from hypothermia, according to a maritime rescue centre in Russia’s Far East.

The Dalniy Vostok freezer trawler had 132 people on board when it sank, reports the BBC.

Some 78 of the crew were Russian, with the remainder coming from countries including Latvia, Ukraine, Myanmar and Vanuatu.

The Dalniy Vostok went down in the Sea of Okhotsk, 330 km (205 miles) west of Krutogorovsky settlement.

Drifting ice may have holed the vessel, according to Russian emergency services.

Water flooded the engine compartment and the trawler then sank within 15 minutes, a local branch of the Russian Emergencies Ministry said.

Some two dozen ships and a rescue helicopter are involved in searching for remaining survivors in freezing waters around zero degrees C (32degF).
