Burkina Faso has suffered attacks most often attributed to unidentified armed individuals. These attacks occur in an area which is under the influence of terrorist groups as well as criminal groups. Instability does not stem from a prior armed conflict, but from a continuous deterioration resulting from unclaimed attacks. The challenge then is to know whether international humanitarian law (IHL) can apply in a context where the perpetrators of violence are not identified. This requires visiting the conditions of applicability of IHL in non-international armed conflict to assess their relevance in a context of production of violence without identification of the perpetrators.
