At least 34 people were killed and eight were missing after a tourist boat capsized in bad weather in Vietnam on Saturday, state media reported. The Wonder Sea boat was carrying 48 passengers and five crew members for a sightseeing tour of Ha Long Bay, a popular destination for visitors. The boat turned upside down because of strong winds during a sudden thunderstorm, media said. Rescue workers recovered the 34 bodies near the site of the capsizing, the VNExpress newspaper said. Authorities said that 12 people were saved, but later corrected that number to 11. One of the survivors was a 14-year-old boy who was rescued four hours after being trapped in the overturned hull. VNExpress said that most of the passengers were tourists, including about 20 children, from Hanoi, the country’s capital. A tropical storm is moving toward the area. A national weather forecast said that Storm Wipha was expected to hit Vietnam’s northern region, including Ha Long Bay's coast, next week.
