The National Intelligence Sevice (NBD) has been on high alert since last November after a raid on a mosque in Winterthur, Zürich in northern Switzerland uncovered an ISIS sleeper cell. Police swarmed on the An-Nur Mosque and made a number of arrests after it was claimed an Imam had been calling for the murder fellow Muslims who did not attend prayers. Switzerland is "not one of the primary targets" for Islamist terrorists, however they are "part of the enemy" say experts who warn that the country's famous red and white flag was recently shown in an ISIS propaganda video.

Law enforcement had been looking into the backgrounds of 200 people in 2015, but that number has shot up to 480, according to local reports. And the NBD is now looking into around 100 incidents per day as they track suspects both on the ground and online. Local reports suggest that the authorities are looking at lone wolf jihadis and trained ISIS operatives who may have returned from Iraq and Syria.

Swiss based human rights expert and found of Forum for a Progressive Islam Saïda Keller-Messahli revealed the an'Nur mosque is not a unique example. She said: "There is a whole network of radically-oriented mosques in Switzerland. "The Muslim World League is behind it, training young imams and sending them out into the world. "These are true wandering preachers, who are not only active in Switzerland, but also in Austria, Germany, Norway and Denmark.

"The network is a hub for Salafists. "The Swiss authorities make a big mistake of not looking into the mosques. "The image of the pitiful backyard mosques is no longer true. "Currently, new mosques are being built at the cost of several million francs, most recently in Volketswil, Netstal and Wil. "The idea that these amounts come from members of the mosques is simply a lie - they come from the Muslim World League and its organisations, for example in Geneva, with the clear intention of spreading Salafist thought here".

Last August French Prime Minister Manuel Valls says the country is to shut down mosques, cut foreign funding and police the content delivered in sermons in a massive crackdown on Islamic fundamentalism. The comments came following the murder of 86-year-old French Catholic priest Father Jacques Hamel who was killed on the altar during morning mass last Tuesday and three separate massacres in the country in just over a year. In a newspaper interview Prime Minister Valls says the Republic has been forced to intervene to drive out the "poison" of radical Islamism. He announced plans to shut down mosques supporting Salafism, an ultra-orthodox religious-political ideology based on a belief in "physical" jihadism practised by some followers of the Sunni faith.
