Paris: A passport found near the body of one of the Stade de France suicide bombers may have belonged to a Syrian regime soldier killed several months ago, a source close to the investigation told AFP.
The passport is in the name of Ahmad al-Mohammad, born September 10, 1990 in the Syrian city of Idlib.
French investigators say all indications point towards the fact he was a soldier loyal to Syrian President Bashar al-Assad.
The source, who spoke on condition of anonymity to AFP, said the passport was either taken or fabricated based on a real identity.
It was registered on the Greek island of Leros on October 3, and was seen again in Serbia and Croatia in the following days.
Both Greece and Serbia are on the so-called Balkan migrant route used by more than 800,000 people desperately fleeing war and misery this year.
The passport was found near the body of one of the three suicide bombers who blew themselves up outside the Stade de France national stadium north of Paris on Friday.
Several far right political groups across Europe have presented its discovery as an argument against welcoming migrants into Europe.
France's anti-immigration National Front leader Marine Le Pen called for an "immediate halt" to new arrivals, while Germany's xenophobic PEGIDA movement drew thousands to their latest anti-Islam rally.
But Germany's government said the Islamic State group may have intentionally sought to create tensions by using the passport "to politicise and radicalise the refugee question".
