Some interesting images:
This one says “Terror has no religion”.
The next one says “No to violence”.
These are all from the website noterror.info. The website also has a series of startling black and white posters with an eerie film noir flavour to them.
The website appears to be still under construction, for example, no information is given on sponsorship, although it appears to be written by people who identify themselves as Moslem. It should be interesting to see how it develops.
