The German police is holding a recruitment event in a mosque controlled by the extremist Milli Gorus movement. Milli Gorus was founded in Turkey in 1969 by the politician Necmettin Erbakan, whose religiously-oriented parties were banned by the Turkish government for violating Turkish laws on secularism. The movement, which has since spread around the world along with Turkish colonist populations, aims at overthrowing the existing secular order and replacing it with an Islamic one, with borders melting away to form one grand Islamic nation. It is generally anti-Western and antisemitic.
Even the German agencies for protection of the constitution have been critical of the movement in their annual reports. But that doesn't seem to have deterred the police from seeking new recruits from among its ranks.
