Malaysia Airlines says a flight from London to Kuala Lumpur has experienced severe turbulence, causing minor injuries to some passengers and crew.

The airline said there was a "brief moment of severe turbulence" when flight MH1, with 378 people on board, flew over the Bay of Bengal on Sunday.

It said in a statement that the flight landed safely in Kuala Lumpur, and that a small number of affected passengers and crew were given immediate treatment. It provided no further details and airline officials couldn't be immediately reached for comment.

A passenger, Harith Azman, posted photos on Facebook showing fallen food carts and a damaged hand rest. He said his father was in one of the plane's bathrooms at the time and hit his head on the ceiling.
