VLADIVOSTOK, October 31 (RIA Novosti) - Russian authorities have extended until Tuesday night a search for the missing sailors from the Sinegorye cargo ship that sank in the West Pacific a week ago, rescuers in Vladivostok said Tuesday.

The Sinegorye, which was transporting timber, sank October 23 in the Sea of Japan, around 80 nautical miles off South Korea's east coast, when a sudden heavy storm broke out. Eleven sailors out of the 18-man crew were found alive and five were found dead. The other two have not been found.

"Good weather conditions, zero wind and excellent visibility in the search area have prompted the extension of the search by one day, until 6:00 p.m. local time (11 a.m. Moscow time/8 a.m. GMT)," a spokesman for the regional rescue center in the port of Vladivostok said.

He said the Russian ships Mashuk and Suvorovets have left North Korea's territorial waters, where several bodies carried there by a northwesterly stream were found over the weekend.

South Korea's ships will conduct a daylight search in the country's territorial waters, the spokesman said.
