Australian PM Tony Abbott has said the "baffling mystery" of Flight MH370 is closer to being solved, after Malaysia announced that a fragment found in Reunion was part of the missing plane.
PM Najib Razak said experts examining the debris in France had "conclusively confirmed" it was from the aircraft.
However investigators have stopped short of confirming the link, saying only that it is highly likely.
Australia says it remains confident it is searching in the right area.
The Malaysia Airlines plane was travelling from Kuala Lumpur to Beijing on 8 March 2014 when it vanished from radar. It had 239 people on board.
