France decided on Saturday to expel Swiss Islamist preacher Hani Ramadan, the grandson of Ikhwan founder Hassan El Banna, for posing “a serious threat to public order,” AFP reports. Ramadan was arrested at a conference in Colmar, France, on the grounds that he had previously “adopted behavior and made remarks which pose a serious threat on French soil,” according to the French Interior Ministry. Ramadan’s brother, Tariq Ramadan, has also been barred from entering the US.
