Hans-Georg Maassen, Germany’s domestic intelligence chief, warned on Sunday that many of the wives and children of German “Islamic State” (IS) fighters “identify deeply” with jihadism and would pose a major security risk if they return home. In an interview with the Deutsche Presse Agentur (dpa) news agency, the head of Germany’s Office for the Protection of the Constitution (BfV) said that although there has not been a major wave of Germans with IS-ties returning home, it was crucial to have security procedures in place. “There are children who have been brainwashed and highly radicalized at ‘schools’ in IS-held areas,” Maassen said. “It’s a problem for us because many of these kids and teenagers can sometimes be dangerous. Maassen’s remarks followed reports in the German media last week that the government was exploring plans to repatriate the children of German (IS) fighters.
