The international police agency Interpol confirmed on March 9 that at least two passports - Austrian and Italian - recorded in its Stolen and Lost Travel Documents (SLTD) database were used by passengers on board the missing Malaysia Airlines flight.

They were added to the database after their theft in Thailand in 2012 and 2013, respectively.

As no country had contacted Interpol regarding these two stolen passports between the time they were entered into Interpol's database and the departure of flight MH 370, Interpol is unable to determine how many other occasions these passports were used to board flights or cross borders.

While checking all documents used on the flight, Interpol also discovered some suspect passports.

Interpol Secretary General Ronald K. Noble said his agency is making all needed resources available to help relevant authorities in Malaysia and countries concerned find out what happened with the missing jetliner.

It is currently in contact with its National Central Bureaus in the involved countries to determine the real identities of the passengers who used these stolen passports to board the missing flight, he said.

The search is continuing for Malaysia Airlines’ Boeing 777-200 aircraft which suddenly went missing en route from Kuala Lumpur, Malaysia to Beijing, China on March 8. On board were 12 crew members and 227 passengers. Six countries have sent their aircraft and ships to join in the search.-VNA
