Investigators have started examining debris that are believed to be from the tail end of the missing Malaysia Airlines flight MH370 after the objects were discovered off the coast of Mozambique, in the southern Indian Ocean.

Flight MH370 inexplicably disappeared almost exactly two years ago, en route from Kuala Lumpur to Beijing on 8 March, 2014 with 239 people on board.

The newly-discovered debris is now on its way to Malaysia for further examination, after investigators said the object with the words "NO STEP" could be from the plane's horizontal stabilizer – a wing-like part attached to the tail.

The debris was found on a sandbank in the Mozambique Channel, the body of water between the Eastern African country and the island of Madagascar. The area is close to where the only confirmed piece of debris, a flaperon, was found in July 2015 in the Reunion Island.

'Too speculative to comment'

Investigators in Malaysia, Australia and the US have looked at photographs of the latest object and sources told NBC News the early photographic analysis suggests it could have come from the doomed Boeing 777.

Australia's Joint Agency Coordination Center told the broadcaster it was aware of the discovery and arranging for a thorough examination. Malaysia Airlines, meanwhile, said it was "too speculative at this point" to comment.

Sources said Boeing engineers are looking at the photos, but the airline has so far declined to comment.

Malaysia has confirmed that there will be no official memorial service for the missing flight MH370 this year, as the jet's disappearance will become aviation's biggest unsolved mystery.
