German spy says ISIS sending fighters disguised as refugees

Islamic State militants have slipped into Europe disguised as refugees, the head of Germany's domestic intelligence agency (BfV) said on Friday, a day after security forces thwarted a potential IS attack in Berlin.
Hans-Georg Maassen said the terrorist attacks in Paris last November had shown that Islamic State was deliberately planting terrorists among the refugees flowing into Europe.
"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 reporters.
"We are trying to recognize and identify whether there are still more IS fighters or terrorists from IS that have slipped in," he added.
