Mortar round explodes during military training in Transdniestrian school TIRASPOL. Dec 7 (Interfax) - A mortar round reportedly blew up in a school in the breakaway province of Transdniestria on Thursday when eleventh grade pupils were studying a mortar's operation during a basic military training lesson, a Bendery police spokesman told Interfax. One student was injured in the incident. Police and experts of the Joint Peacekeeping Forces are working at the scene because Bendery is a part of the security zone. Three explosions were reported in Transdniestria earlier this year. A good lesson in life - don't hand out heavy weapons for schoolkids to play with. Whatever next?
