The tragedy in Nice is the latest horrifying terrorist attack to hit France, with hundreds of people falling victim to extremists. Authorities are waging a frantic battle against the plague of radicalism, at the same facing criticism from citizens, who are upset by the limitation of their liberties.

Will French citizens now have to accept this kind of threat as a part of their daily lives? And with a strong backlash against the Muslim community now inevitable - could a civil war be ripening in France? We ask former intelligence chief at France's External Security Agency, Alain Juillet, on Sophie&Co today.
