The Islamic Center Hamburg (IZH) was under investigation for several months over its alleged support for Lebanon’s Hezbollah group which is backed by Iran. Hezbollah is classified as a terrorist group by Germany.

German Interior Minister Nancy Faeser said on Wednesday that the Islamic Center Hamburg (IZH) would be banned for propagating extremism and that its famous “Blue Mosque” was being searched by police.

“It is very important to me to make a clear distinction here: we are not acting against a religion,” Faeser said, but just against a group accused of undermining the German state as well as women’s rights.

The Imam Ali Mosque, known locally as the Blue Mosque, is one of Germany’s oldest mosques and is operated by the IZH.
