A Singapore Airlines flight from Osaka to Singapore was hit by strong turbulence on Tuesday, causing injuries to 14 people on board, including one Japanese, the airline said.

Flight SQ 615, which was carrying 268 passengers and 13 crew on board, had "encountered sudden severe turbulence resulting in injuries to several passengers and crew."

An airline spokesman said the turbulence occurred about an hour before the Airbus 330 was due to land in Singapore. The plane landed in Singapore at 5:17 a.m. local time, as scheduled.

A total of 12 passengers and two crew members were hurt in the incident, mostly due to head and neck injuries and abrasions.

Those injured were taken to the airport's clinic for outpatient treatment, including a Japanese male passenger.

One of them was sent to a hospital for further assessment.
