A 15-year-old student carried out a knife attack at the Notre-Dame-de-Toutes-Aides private high school in Nantes, France, killing a female student and injuring three male students.
The attacker, dressed in black with a helmet and ski mask, was subdued by teachers and handed over to police. Authorities have not disclosed the motive. French media reported the teen had emailed a document to all students before the incident, though it contained no mention of the attack.
