There are unconfirmed reports that the Vietnamese air force have spotted a floating object which may be part of the missing Malaysian Airlines 777-200 which disappeared en route from Kuala Lumpur to Beijing with 239 people on board.

Vessels from several countries are still searching a vast section of ocean between China, Vietnam and Malaysia for debris from the plane. One report states the object is thought to be an aircraft door. It was spotted off the country's south coast.

Meanwhile, Chinese media have reported several cases of relatives calling the mobile phones of people thought to be aboard flight MH370. The phones connect but no one answers. Some of the calls were filmed being made on Beijing Television.

More soon.
