A submarine scanning the ocean floor for signs of a missing Malaysian airliner is two-thirds of the way through its search but has yet to find the plane, officials say.

The Bluefin-21 submarine was to embark on its ninth search mission on Monday.

Malaysia Airlines flight MH370 went missing in March as it flew from Kuala Lumpur to Beijing carrying 239 people.

On Monday another Malaysia Airlines flight was forced to land after one of its tyres burst on take-off.
