Two men who boarded the missing Malaysia Airlines flight using stolen passports have been identified as Iranians and were "probably not terrorists", according to Interpol.
One of the men travelling on a stolen passport is believed to have been looking for a "better life" in Europe.
Military radar suggests the missing Malaysia Airlines plane turned west, away from its planned route, before vanishing.
