Germany's federal police say authorities are investigating multiple cases in which suspected Islamic terrorists entered the country while it was letting in massive amounts of refugees.

According to Reuters, the head of Germany's domestic intelligence agency Hans-Georg Maassen, said that ISIS sent terrorists through the Balkan route from Greece in order to “send a political signal” and increase fears about refugees.

He claimed that ISIS has “more efficient ways” to smuggle in terrorists. Because that's really reassuring.



“I am not telling you a secret when I say that I am concerned about the high number of migrants whose identities we don't know because they had no papers when they entered the country,” Maassen said.



A spokeswoman for the federal police said there had been 369 warnings about possible extremists entering the country. 40 of which were serious enough to warrant federal and state authorities to investigate.
