Thailand's military deployed warships and helicopters on Monday to try to locate 33 marines missing after a corvette sank overnight in choppy waters in the Gulf of Thailand, the navy said.
Three navy vessels and two helicopters were sent to find the missing off Prachuap Khiri Khan province, south of Bangkok, after the HTMS Sukhothai warship suffered an engine malfunction and went down just before midnight about 20 nautical miles off the coast.
An overnight rescue mission in bad weather secured 73 of the 106 people aboard, the navy said, with the remaining 33 forced to abandon ship.
The navy posted images and video footage on its Twitter account showing a group of personnel in orange vests in a black inflatable raft moving away from a ship in darkness as waves swelled around it. It was not immediately clear how many rafts had been deployed.
