The eight people who died in a June accident were found without flotation devices, according to a new report. The two survivors relied on the devices to stay afloat.
The boat, carrying 46 passengers and three crew members, was on a sightseeing tour of Ha Long Bay when a sudden storm caused it to overturn, state media said. Ten people were rescued.
