Winterthur has become a "hot spot" for radicalization and the authorities aren't doing enough to combat it, says a Muslim politician in the city.
In an interview with the Tribune de Genève, Blerim Bunjaku, a socialist politician in the city and himself a Muslim, said the authorities were partly to blame for the rise of radical Islam in Winterthur, which has seen five young Muslims travel to the Middle East to fight for Isis.
"The authorities haven't done enough during the past few years to promote the integration of foreigners," he said.
"Today, young Muslims grow up in Salafi families, cut off from Swiss culture. They see the West as an enemy."
