Some young Swiss converts to Islam are a potential threat to the country's security, according to the head of the Migration Office.
Alard du Bois-Reymond was speaking about the Central Islamic Council (IZRS), founded by young converts in the western town of Biel. The group strongly denies his assertion.
Du Bois-Reymond told the German-language newspaper NZZ am Sonntag that such converts include people who want a "radically different society" and pointed to examples in Britain and Germany where such demands had provided "fertile ground for potential terrorists".
The IZRS was also the subject of a recent highly critical article in the German-language magazine Weltwoche, which described its leader, Nicolas Blancho, as "the most dangerous Islamist in Switzerland".
