The search for the missing Malaysian plane is entering a "new phase", Australia has announced, after the initial undersea search found nothing.

PM Tony Abbott said that "a much larger" area of the ocean floor would now be targeted.

But he said it was "highly unlikely" any wreckage would be found on the surface.

Malaysia Airlines flight MH370 went missing on 8 March as it flew from Kuala Lumpur to Beijing.

The plane, carrying 239 people, disappeared off radar over the South China Sea.
