Europe 1 draws up a sketch of the radicalized person on file, although there are just over 20,000 of them in France. Main risk, according to intelligence services, is that fighters from the Afghan branch of the Islamic State activate sleeper cells or individuals already present on French territory.
Most dangerous radicalized people are found in areas of large metropolises: Lille, Paris, Strasbourg, Lyon, Marseille and Toulouse. Few, if not very few, Islamists actively monitored by the DGSI suffer from mental disorders.
