MH370 Australian investigators said today that two plane parts recovered from the Mozambique coast were "almost certainly" from Malaysia Airlines flight MH370, whose disappearance over two years ago became one of the biggest mysteries in aviation history.

The parts, one from a wing flap and another from a stabiliser panel on the rear of the plane, were found some 220km apart in December and February.

Both parts were identified by their dimensions, distinctive stencilling, and by paint of the same type used by Malaysia Airlines, investigators from the Australian Transport Safety Bureau said.

Flight MH370 went missing on March 8, 2014 en route from Kuala Lumpur to Beijing, with 239 passengers and crew on board. Its final route was tracked to the southern Indian Ocean, where it is presumed to have crashed.

In August 2014, experts confirmed that a part found on Reunion Island east of Madagascar came from MH370, in the first such discovery.

The main body of the plane has never been located despite a massive search of the sea surface and floor, and no bodies have been recovered.

It is still unclear why the plane went so far off course.
