Seventeen passengers and crew have been injured when a Hong Kong Airlines' flight ran into severe turbulence on the way from Indonesia's resort Bali island to Hong Kong.

Trikora Harjo, general manager of Bali's Ngurah Rai airport, says the Airbus A330-200 carrying 204 passengers and 12 crew encountered the turbulence above Kalimantan, Indonesia's part of Borneo.

The plane returned to Bali about 2 ½ hours after it took off and landed safely at 4:34 a.m. (2034 GMT Friday).

It was the second such incident involving Airbus planes over Indonesian territory in the past four days.

On Wednesday, an Etihad Airways flight from Abu Dhabi ran into sudden turbulence as it prepared to land in the Indonesian capital, injuring 31 passengers and a crew.
