LYON, France (AP) — Interpol has released an image of two Iranians who were traveling with stolen passports on a missing Malaysia Airlines jetliner.

The image showed the two Iranian men boarding a plane at the same time. Interpol secretary general Ronald K. Noble the two men traveled to Malaysia on their Iranian passports, then apparently switched to the stolen Austrian and Italian documents.

Noble says the recent information about the men made terrorism a less likely cause of the plane's disappearance, but that did not allay concerns about the ease of travel involving stolen passports.

The men are identified as a 19-year-old (Pouri Nourmohammadi) and a 29-year-old (Delavar Seyedmohammaderza). The 19-year-old is believed to have planned to seek asylum in Germany.
