Malaysian Prime Minister Najib Razak has confirmed the flaperon found on the French island Reunion is a part of the missing MH370, raising hopes of solving the one-year old mystery.

French experts, who are examining the debris, have said there is ‘very high probability’ that it belonged to the aircraft.

The experts confirmed the part belonged to a Boeing 777, the same model as the one that went missing.

Tests on the aircraft part are continuing for the second day.

"Experts confirmed the part belonged to a Boeing 777, the same model as the one that went missing."

The Malaysia Airlines flight went missing in March 2014, on its way to Beijing from Kuala Lumpur carrying 239 passengers.

In the last week of July, the flaperon washed ashore La Réunion in the Indian Ocean, located east of Madagascar and 4,000km from the area where search efforts were focused for the missing aircraft.

Razak said the experts have ‘conclusively confirmed’ the flaperon was from the aircraft, while the Australian prime minister observed the mystery of the Malaysian flight is closer to being solved.

Razak said: "Today, 515 days since the plane disappeared it is with a heavy heart that I must tell you that an international team of experts have conclusively confirmed that the aircraft debris found on Reunion Island is indeed from MH370."

Malaysian Transport Minister Liow Tiong Lai told reporters more plane debris, including a window and aluminium foil, were found on the island. He did not confirm that they belonged to MH370, reported the Guardian.
