Rescuers retrieved a body floating in the sea Tuesday after a boat carrying 30 people capsized off Thailand's southwestern coast, officials said. The search continued for six more people, including five foreigners, reported missing. Authorities and fishermen plucked 23 divers from the sea a few hours after the boat sank early Monday and rushed them to local hospitals, said marine police officer Parinya Kaewplung. The boat was about 12 miles (19 kilometers) off the coastal Phang Nga province when it went down, Associated Press reported.
