Apparently the Ulyanovsk ammunition plant located in Russia had an explosion as soldiers were trying to decommission munitions in one of their arsenals by means of controlled detonations. The Ulyanovsk plant is the manufacturer of Brown Bear and Silver Bear ammunition. This is not supposed to disrupt the manufacture of ammunition because the plant was in the process of being shut down as part of a planned decommissioning. One person was killed and 35 injured in the blast. 3,000 people were evacuated form the area. RTE news has an article on the event.
