Some 1,500-2,000 European citizens have left for Syria to fight, they are also known as ‘foreign fighters’. The level of foreign fighters travelling to Syria to date has been unprecedented in comparison to previous conflicts in the last decades. Member States have implemented repressive measures, such as making it illegal to travel to training camps and withdrawing passports from potential fighters. However, repression alone will not solve the problem. Prevention, signalling and providing programmes to help (potential) foreign fighter to leave the path of violent extremism are necessary as well. These actions are often organised on a local level. Therefore the Radicalisation Awareness Network (RAN) hosted a cities conference for 200 local practitioners and policy makers of European Member States. The aim of the Cities Conference was the exchange of knowledge and practices between practitioners of the various European cities1on how to deal with the foreign fighter phenomenon before, during and after travel and provide recommendations on a local, national and EU-level. The programme of the day and the conference paper that was written prior to the meeting are attached to this report.
