Intensive search efforts are under way to try and find flight MH370, which vanished from radar en route to Beijing from Kuala Lumpur almost three days ago, with 239 people on board.

None of the debris and oil slicks spotted in the water have so far been linked to the disappearance - but how could a plane vanish without a trace?

BBC transport correspondent Richard Westcott reports.
