A Norwegian ship owner says one if its cargo vessels has sunk off Vietnam. Bergen-based Gearbulk says only one of the 19 Filipino crew members was known to have survived.

A Vietnamese rescue official, speaking on condition of anonymity because he was not authorized to speak to the media, says two bodies have been recovered.

Gerbulk said Saturday the "Bulk Jupiter" was 155 nautical miles off Vietnam, en route from Malaysia to China, with a cargo of bauxite when it sent a distress signal that was picked up by the Japanese Coast Guard.

The Vietnamese official says rescue operations were hampered Saturday by hazy weather and high waves.
