Germany's domestic intelligence agency (BfV) said on Friday that Islamic State militants have slipped into Europe disguised as refugees, after the spy agency thwarted an ISIS attack in-country, reported Reuters.
The head of the agency, Hans-Georg Maassen, said, "Then we have repeatedly seen that terrorists ... have slipped in camouflaged or disguised as refugees. This is a fact that the security agencies are facing," Maassen told ZDF television.
"We are trying to recognize and identify whether there are still more IS fighters or terrorists from IS that have slipped in," he added.
