Arson attacks in Grenoble
The wave of arson attacks in Grenoble is a series of arson attacks in France that have occurred since March 2017, in the Grenoble metropolitan area, the most publicized of which were those of the warehouse of the Isère Gendarmerie group and the France Bleu Isère radio station. All of these fires were meticulously prepared; some were not claimed, but most were by an anarchist movement.
