KUALA LUMPUR – Plane wreckage found in an Indian Ocean island is “very likely from a Boeing 777”, Malaysian Prime Minister Najib Razak said on Thursday, as speculation mounted that it could be debris from missing flight MH370. “Initial reports suggest that the debris is very likely to be from a Boeing 777, but we need to verify whether it is from flight MH370,” Najib said in a statement on his Facebook page. Malaysia Airlines was operating a Boeing 777 on the ill-fated flight, which vanished without a trace in March last year, while en route from Kuala Lumpur to Beijing in one of the most baffling 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, roughly 3,700km (2,300 miles) from France’s Reunion Island. There have been four serious accidents involving 777s in the past 20 years since the widebody jet came into service. Only MH370 is thought to have crashed south of the equator. French authorities said they were examining the debris, found washed up on Reunion Island east of Madagascar on Wednesday. “No hypothesis can be ruled out, including that it would come from a Boeing 777,” the Reunion prefecture and the French Justice Ministry said in a joint statement on Thursday.
