Teen loses hand in stun grenade blast at French school protest

A 15-year-old boy lost his hand after a stun grenade detonated during school protests in Lens, northern France, on Monday. The device exploded in his left hand near a school, and he was hospitalized in Lille with non-life-threatening injuries. Up to 250 young people had gathered at the Auguste-Béhal school when the incident occurred. Police watchdog IGPN has launched an investigation into whether riot police met criteria for using the grenade, as the prosecutor could not confirm if the student picked it up or it was thrown at him. Hundreds of schools remain closed this week amid nationwide student protests over heatwave conditions and teacher shortages. Authorities report dozens of schools ransacked, with some teachers assaulted, while the education minister accused unrelated activists of infiltrating the movement.
