Despite the rumors that tricked more than half the state governors in the USA into enacting racist anti-Syrian policies, there is no evidence that the Paris attackers came from outside the EU.
One attacker had a seemingly fake Syrian passport on his body, which is consistent with the idea that Daesh want to provoke racist retaliation against Muslims around the world, to convince moderate Muslims that there can be no peaceful co-existence with secular Western states. The tactic has been effective: the terrorists used it to recruit the majority of US state governors to support Daesh's goals.
"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."
