A Russian drone struck a school in Kyiv as Moscow continued its intense aerial attacks on Ukraine. Children and staff had taken shelter before the strike, and no casualties were immediately reported. The attack came just two days after a school in Sumy was struck by Russian glide bombs after students and teachers were evacuated.The strikes come as Russia deploys increasingly sophisticated jet-powered drones, including a new weapon that Ukrainian officials say is designed to target high-voltage infrastructure. As winter approaches, Ukraine is racing to strengthen its defences while Russia increases pressure from the skies.
