The government would provide assistance to the passengers and their families, said Singapore’s Transport Minister Chee Hong Tat.

After about 11 hours of flying time, the aircraft sharply dropped from an altitude of about 37,000 feet (11,278 metres) to 31,000 feet (9,449 metres) within five minutes as it crossed the Andaman Sea and neared Thailand, according to reports.

Kittikachorn said, the flight fell into an air pocket while cabin crew were serving breakfast before it encountered turbulence, prompting the pilots to request an emergency landing.
