The owner of a Syrian passport found near the body of one of the terrorists who blew themselves up in Paris allegedly entered Europe posing as a refugee.
Serbian media claims Ahmed Almohammad, 25, whose Syrian passport was found on the body of a suicide bomber, was one of three terrorists to blow themselves up outside the Stade de France.
The newspaper, Blic, claims the man arrived with another of the bombers in Europe through the Greek island of Leros on 3 October. They say he entered Serbia from Macedonia on 7 October.
Serbian authorities have confirmed the man entered Serbia from Macedonia on 7 October. On 8 October, he was registered in Croatia, before moving through Hungary and Austria.
French security forces reportedly asked Serbian authorities for help identifying the man.
Greek website Protothema published pictures of ferry tickets showing a second man, Mohammed Almohammad, who had travelled with Ahmed Almohammad and may be a relation.
The Greek media organisation also published photos of a database showing the pair's travel tickets.
A Greek police source said the passport's owner had arrived on a small vessel from Turkey with a group of 69 refugees, and had his fingerprints taken by Greek officials.
It is not known whether Mohammed Almohammad was involved in the atrocity. He has not yet been named as one of the bombers by authorities.
The passport may have been bought or stolen. It is also possible that the Syrian passport may have been a forgery.
