Fate of missing Malaysia jet 'a mystery' as search widens

Malaysia says it is widening the search for the airliner that disappeared with 239 people on board a flight to Beijing on Friday night.

It says there have still been no confirmed sightings of any wreckage and all possibilities are being considered, including hijacking.

The authorities say they are examining CCTV footage of two passengers who were travelling with stolen passports.
