During a village celebration in the Savoy region of France, a fireworks rocket, instead of launching vertically, took off horizontally and burst in the assembled crowd. About 10 members of the public were slightly burned by shattered rocket pieces. Emergency responders accompanied the injured to the closest medical office for diagnosis. Three individuals, including a young girl, had to be hospitalised. According to initial reports, a support box that had shifted position would have modified the rocket’s trajectory. The following day, all those injured were allowed to return home; the gendarmerie conducted an investigation.
