The transport ministers of Australia and Malaysia say two plane parts found in Mozambique almost certainly came from missing Malaysian Airlines flight MH370.
The two pieces of debris were found separately by members of the public and were flown to Australia for analysis.
Australian's Darren Chester said the finds were "consistent with drift modelling" of ocean currents.
MH370 vanished in March 2014 with 239 people on board.
It went out of contact while flying from the Malaysian capital Kuala Lumpur to Beijing. Satellite data suggests it likely went down in the southern Indian Ocean after veering off course for unknown reasons.
The fate of the plane, its passengers and crew remains one of aviation's biggest unsolved mysteries.
One of the parts retrieved in Mozambique was found on a sandbank by an amateur US investigator in late February. That find prompted a South African tourist to come forward with a piece he found in Mozambique in December.
