"Based on their new analysis, Inmarsat and the AAIB have concluded that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean, west of Perth," he added.

Malaysia Airlines, in a statement to the relatives of all those on board, stated: "We deeply regret that we have to assume beyond any reasonable doubt that MH370 has been lost and that none of those on board have survived... we must now accept all evidence suggests the plane went down in the Southern Indian Ocean."

It, however, stated that the ongoing multinational search operation would continue, "as we seek answers to the questions which remain".
