What would you do if someone you knew was being radicalised?

As part of this week's focus on jihadi violence, we will be talking to a group of young muslims in the United Kingdom about why more and more young people across Europe are turning to extremism. We will hear how Muslims feel about this and discuss what people do when they find out that someone close to them is being radicalised. We want to find out what conversations are being had. What do people hear about their friends? Why does radicalisation happen? And is enough being done within the Muslim community and the wider society to try and prevent this from happening?
