Thai navy frigates and helicopters were on Monday searching for 31 sailors after a naval vessel sank, with dozens of others having been hauled from choppy waters in the Gulf of Thailand.
The search and rescue operation involved two Seahawk helicopters, two frigates and one amphibious ship.
The HTMS Sukhothai capsized late on Sunday night as it was patrolling the Gulf of Thailand, about 37km from Bang Saphan pier in Prachuap Khiri Khan off the nation’s south-eastern coast, reports Straits Times.
Some sailors survived by jumping into a life raft at night, according to images shared by the Royal Thai Navy, which said 75 people had been rescued.
According to navy spokesman Admiral Pogkrong Montradpalin, 31 sailors were still missing on Monday afternoon.
A statement from the Royal Thai Air Force later Monday said they were also assisting in the operation, without giving details.
Thai Prime Minister Prayut Chan-o-Cha said the cause of the incident was being investigated.
