Teen loses hand after picking up stun grenade at French school protest

A 15-year-old student in Lens, France, lost his hand when a projectile he picked up exploded during school protests. The incident occurred this morning, and the boy is hospitalized in Lille but not in life-threatening condition. French media report the projectile was a stun grenade thrown by riot police, which the boy reportedly attempted to throw back. The protests involved 200-250 students throwing stones and fireworks at police, prompting a mobile unit deployment. Nationwide, 589 schools saw demonstrations today, with 190 injuries since protests began last week. The demonstrations address education issues like building maintenance, teacher shortages, and large classes. Two teenagers were arrested for separate incidents, including throwing a stone that may blind a passerby. Further protests are expected tomorrow, and unrest also occurred in Liège, Belgium.
