"I cannot give the all-clear with Daesh [ISIS].
We must further take into account that Daesh [ISIS] could launch an attack in Germany at any time”, Thomas Haldenwang, president of the German Federal Office for the Protection of the Constitution (BfV), told the German outlet Die Welt am Sonntag.
Moreover, he warned that there are still underground ISIS groups in Syria and Iraq, and that the security service keeps getting information about people planning attacks.
The number of people that Bfv has red flagged as possibly dangerous radical Islamists grew by 300 people last year, Haldenwang said.
2,240 people are classified as potential terrorists who could carry out or support an attack at any time.
"Keeping track of all these people around the clock is not possible.
You would need up to 40 officers per person, so we could focus on those we consider particularly dangerous”, he told the outlet.Bfv, according to Haldenwang, is also paying special attention to the children of German ISIS returnees coming back from the Middle East.
