Saint-Denis-De-La-Reunion (France), July 30 (Reuters): Malaysia is "almost certain" that plane debris found on Reunion Island in the Indian Ocean is from a Boeing 777, the deputy transport minister said today, heightening the possibility it could be wreckage from missing Flight MH370.

The object, which appeared to be part of a wing, was being sent to offices of France's BEA crash investigation agency in Toulouse to verify if was indeed the first trace of the lost plane to be found, Malaysian Prime Minister Najib Razak said.

Malaysia Airlines was operating a Boeing 777 on the ill-fated flight, which vanished in March last year en route from Kuala Lumpur to Beijing in one of the most baff-ling mysteries in aviation history.

The plane was carrying 239 passengers and crew.

Search efforts led by Australia have focused on a broad expanse of the southern Indian Ocean off Australia. Reunion Island, where the debris was found washed up yesterday, is a French overseas department roughly 3,700km away, east of Madagascar.

"The location is consistent with the drift analysis provided to the Malaysian investigation team, which showed a route from the southern Indian Ocean to Africa," Najib said in a statement.

Aviation experts who have seen widely circulated pictures of the debris said it may be a moving wing surface known as a flaperon, situated close to the fuselage.

"It is almost certain that the flaperon is from a Boeing 777 aircraft. Our chief investigator here told me this," Malaysian Deputy Transport Minister Abdul Aziz Kaprawi told Reuters.

Abdul Aziz said a Malaysian team was heading to Reunion Island, about 600 km east of Madagascar. Australia's deputy Prime Minister Warren Truss said the object had a number stamped on it that might speed its verification.
