(Israel Hayom/Exclusive to JNS.org) Supporters of the Islamic State of Iraq and Greater Syria (ISIS) terror group clashed last week with Kurdish Yazidis in North Rhine-Westphalia, the state housing Germany’s largest Muslim population. The violence – which comes amid threats by a German jihadi to blow up an American nuclear weapons storage facility in Germany – has counter-terrorism officials concerned that radical Muslims are deliberately exploiting the ethnic and religious tensions in the Middle East to stir up trouble on the streets of Europe. German authorities have long warned of the threat posed by Salafism, a radically anti-Western ideology that seeks to impose Islamic Shariah law in Germany and other parts of Europe.
