A plane door has reportedly been found washed up on Reunion Island in the Indian Ocean.
Sky News reports it's not known if the door is from the doomed Malaysia Airlines flight MH370 or if it's from a Boeing 777.
It has been discovered on a different area of the island where a two-metre wing part washed up days ago.
That part has now been arrived at a French laboratory for analysis to determine whether it is from MH370, which disappeared en route from Kuala Lumpur to Beijing in March last year with 239 people on board, including six Australians.
If confirmed as being from the missing plane, it would be the first breakthrough in a case that has baffled aviation experts for 16 months.
Malaysian and French experts will on Wednesday begin to analyse the wing part, as well as fragments of a suitcase discovered nearby.
