Danish Prime Minister Helle Thorning-Schmidt has said that an attack on Jewish citizens is an attack on Denmark. So far Europe has reacted with a show of unity and a determination to defend its values and not to be intimidated. At the same time Governments are also encouraging citizens to be tolerant towards people with different religious beliefs. But voices critical of false interpretations of religion that sow the seeds of hatred have also been raised. There is much debate on how to deal with religious extremism?

Following the release of a video which appears to show the decapitation of 21 Egyptian Coptic Christians Cairo has launched military strikes against an IS-affiliated group in Libya. The video showing the execution of Coptic Christians appears to have been shot on the Mediterranean coast just across the water from Europe. The message is clear the terrorists have Europe in their sights. How close are they? Three Muslims were also killed last week in a shooting in the US which media and authorities have been reluctant to define as terrorism or even as a hate crime. How dangerous is it to practice a different faith? Is the peaceful co-existence of different cultures and faiths under threat?
