Terrorism is a dangerous phenomenon for Sahelian countries and Mali in particular. It creates desolation wherever it exists, preventing the development of the entire Sahel region. Like everything else that is violent, terrorism has an impact on the psychological state of those who have to endure it. It determines a certain emotional and intellectual state in them, which we felt should be taken into account by psychologists. It is this state of terror that invades the minds of victims of terrorist attacks that is the subject of the present research. It's a way of drawing the attention of authorities and professionals to the impact of terrorism, its manifestations, its characteristics and how victims are cared for. In addition to the resilience of the Malian population, the phenomenon of Stockholm syndrome in hostage-taking by terrorists is one of the situations overlooked in this book, which aims to provide guidance for analysis and solutions.
