Malaysia is investigating four names on the flight manifest of an airliner that vanished with 239 people aboard, as it probes a possible terror link.
Transport minister, Hishammuddin Hussein's comments looked set to fuel speculation over whether a security breach or hijack may have played a role in what would be Malaysia's worst-ever aviation disaster.
Those fears arose, after it emerged yesterday that two people boarded the missing Malaysia Airlines flight with stolen European passports.
Flight 370 went missing somewhere between the coasts of Malaysia and Vietnam early Saturday morning en route overnight from Kuala Lumpur to Beijing.
Hishammuddin said Malaysia was in touch with the counter-terror agencies of the US and other countries.
There has been no terrorist claim or other evidence of a hijack or attack.
