"Germany announced a ban on Islamic State on Friday, saying it aimed to prevent the militants from recruiting young jihadists in Germany, especially via the internet, or from using combat-hardened fighters returning to Europe to carry out attacks.
Coinciding with the launch of a broad U.S. campaign against the Sunni militants, which could include air strikes in Syria as well as Iraq, Germany introduced an immediate ban making all IS propaganda, symbols and activities illegal."
