The Civil Aviation Department of Hong Kong has received a pilot's report that a large amount of debris was spotted in Vietnamese waters.

The pilot, flying a Hong Kong to Kuala Lumpur plane, says the debris is located about 60 kilometres southeast of Vietnamese city Vung Tau, some 500 kilometers from where the Malaysian jetliner lost contact with air traffic controllers. The department has submitted the message to the relevant authorities.

No information has been confirmed so far to suggest terrorism is behind the loss of contact with Malaysia Airlines flight MH370, still unlocated as of Sunday afternoon.
