Distraught relatives wait to hear news more than 24 hours after the presumed crash.

Missing Malaysia Airlines flight MH370 may have turned back from its scheduled route before vanishing from radar screens, deepening the mystery surrounding the fate of the plane and the 239 people aboard.

The plane lost communication with air traffic control two hours into its journey from Kuala Lumpur to Beijing at 5.30pm GMT on Friday.

It has now emerged that two passengers, who both bought tickets for the flight at the same time, were travelling on passports – one Italian and one Austrian – which had been stolen in Thailand several years ago.

Investigators are studying CCTV of the 'suspect' passengers for clues.

After more than 24 hours there is still no sign of a wreckage of the Boeing 777-200, which is now presumed crashed in the sea between Malaysia and Vietnam.
