Debris found on Reunion Island in the Indian Ocean is “conclusively” from missing Malaysia Airlines flight MH370 Malaysian prime minister Najib Razak has confirmed.

The Boeing 777 aircraft was travelling from Kuala Lumpur to Beijing on March 8th 2014 when it vanished from radar.

All 239 people on board are presumed dead.

Following analysis of the debris in France, Australian prime minister Tony Abbott has the “baffling mystery” of Flight MH370 is now one step closer to being solved.

He added: “The find does seem to indicate the plane did come down more or less where we thought it did.”

Debris – in the form of a wing part known as a flaperon - was found on the remote French island a week ago and was the first possible trace of the airliner since it vanished last year.

A statement from Malaysia Airlines said: “This is indeed a major breakthrough for us in resolving the disappearance of MH370.

“We expect and hope that there would be more objects to be found which would be able to help resolve this mystery.”

The airline said its priority would be to continue to provide the latest updates and information to the families and to cooperate with the relevant authorities on the investigation and recovery of the accident.
