In February 2017 , the German Salafist mosque organisation '' Berliner Fussilet-Moscheeverein '' was banned by authorities . Anis Amri , the perpetrator of the 2016 Berlin truck attack , was said to be among its visitors . In March 2017 , the German Muslim community organisation '' Deutschsprachige Islamkreis Hildesheim '' was also banned after investigators found that its members were preparing to travel to the conflict zone in Syria to fight for the Islamic State . According to the Federal Agency for Civic Education , these examples show that Salafist mosques not only concern themselves with religious matters , but also prepare serious crimes and terrorist activities
