Chilean President José Antonio Kast says his government will tighten school security after two recent incidents involving weapons and amid growing concern about school violence. The move on Monday follows a fatal knife attack that killed one person and injured four. A separate case on Monday involved a 15-year-old who was detained while attempting to enter a school with a loaded gun. Authorities are considering stricter access controls, backpack inspections and deployment of metal detectors. Such incidents are rare in Chile. But recent cases including a 2024 explosion and a 2025 school shooting have raised safety concerns nationwide.
