Violence in the name of religion has become an urgent global issue, with growing debate about how to stop it.
A recent congress of world religious leaders in the capital of Kazakhstan is one example of new efforts to find solutions.
The UN Secretary General, Ban Ki-Moon, urged the delegates for their help.
“The scourge of violence in the name of religion calls for concerted action by governments, religious communities, civil society and the media,” he said.
And that is one of the key concerns: that security forces are often alone in the fight against extremism.
