Excerpt:
Violence between Islamists and Kurds on Germany's streets this week has prompted some conservative politicians to call for a ban on demonstrations, amid fears further planned protests will get out of control.
Violence broke out between Yazidi Kurds and Muslim fundamentalists in Celle, Lower Saxony on Monday night, and there was a mass brawl involving 800 people Kurds and Islamists in Hamburg on Tuesday.
The trouble continued throughout the week but tensions appeared to have decreased in Hamburg on Thursday after 1,300 police officers were deployed overnight to keep Kurds and Muslim fundamentalists apart.
