A Malaysia Airlines A330-300 carrying 271 passengers has been forced to make an unscheduled landing in Hong Kong after an onboard generator suffered a technical fault.
Flight MH3066 took off from Kuala Lumpur at 2337 local time (1537 GMT) last night bound for Seoul Incheon airport.
An "inoperative" generator saw the flight divert to Hong Kong International Airport, where it made a safe landing at 0300 this morning.
MAS said there was no loss of power on the A330 because an auxiliary generator took over.
The return flight from Seoul to Kuala Lumpur was cancelled and all passengers on both legs have been transferred to other flights.
A spokeswoman for Hong Kong International said the aircraft landed less than 30 minutes after it notified the airport and said it was not classified as an emergency landing, although emergency services were on standby.
The incident comes as the search for Malaysia flight MS370 continues in the remote south Indian ocean off western Australia. That flight, from Kuala Lumpur to Beijing and with 239 people onboard, vanished on March 8.
