INTERVIEW

Killed at the prefecture of Paris, attack against a synagogue in Halle, Germany, stabbing in a mall in Manchester ... Jean-Charles Brisard, president of the Center for Terrorism Analysis, returned Friday at the microphone of Europe 1 on the recent attacks in Europe, emphasizing the relatively new form that terrorism takes today in France and abroad.

"More than 50% of the individuals who have been involved in our country since 2013 were unknown to intelligence files," he says. "The system is perfectible, we must adapt our devices to the reality of terrorism as it is expressed today and for several years now: a diffuse terrorism, local and extremely difficult to predict, anticipate and prevent."
