All of the attackers from Friday’s massacre in Paris so far have been identified as European Union nationals, according to a top EU official. The announcement further casts doubt on the validity of a Syrian passport found near the bodies of a slain attacker.

“Let me underline, the profile of the terrorists so far identified tells us this is an internal threat,” Federica Mogherini, the High Representative for Foreign Affairs and Security Policy/Vice-President of the European Commission, said after a meeting with EU foreign ministers. “It is all EU citizens so far. This can change with the hours, but so far it is quite clear it is an issue of internal domestic security.”

The majority of attackers were identified as French or Belgian nationals. An Egyptian passport was also found, but the Egyptian Ambassador to France said it belonged to a critically wounded victim and not a perpetrator. The Syrian passport caused a ruckus, with some politicians in Europe and the U.S. calling for a halt to Syrian refugee resettlement. An increasing number of state governors are trying to defund the settlement program. American officials told CBS News that the passport might be fake, while British-daily the Independent reported that a man was arrested in Serbia while carrying a Syrian passport with matching details to the one found in Paris.
