UKIP’s Nigel Farage has been warning about this early last year in the EU fake parliament:
Tracing the path of four terrorists sent to Europe by the Islamic State
SALZBURG, Austria — On a crisp morning last October, 198 migrants arrived on the Greek island of Leros, all of them seemingly desperate people seeking sanctuary in Europe. But hiding among them were four men with a very different agenda.
The four were posing as war-weary Syrians — all carrying doctored passports with false identities. And they were on a deadly mission for the Islamic State.
Two of the four would masquerade as migrants all the way to Paris. There, at 9:20 p.m. on Nov. 13, they would detonate suicide vests near the Stade de France sports complex, fulfilling their part in the worst attack on French soil since World War II.
The other two men would not make it that far.
