The infamous Molenbeek borough of Brussels, linked to the attacks in Brussels itself and Paris as well, is seeing a continuing growth in support for radical Islam.
Worryingly, officials believe that it is youngsters who are increasingly supporting the ISIS doctrine, hating the very country that many of them have grown up in.
This mirrors the huge surge in support for radical Islam that has been seen in European nations such as Germany.
An increasingly troubling picture is being painted: disconnected ghettos within a society of multiculturalism encouraged by European governments with a sharp rise in dangerous Islamic radicalism and European security agencies struggling to cope as a result. Europe is becoming a much more dangerous place with radical Islam on the rise.
