An explosion at a storage site for unexploded ordnance at a U.S. military base on Japan’s southern island of Okinawa injured four Japanese soldiers, though the injuries are not life-threatening, officials said Monday. The four soldiers sustained finger injuries while working at a facility that belongs to Okinawa prefecture and temporarily stores unexploded ordnance, mostly from wartime and found on the island, local officials said. One of the harshest battles of World War II was fought on Okinawa. Prefectural officials said the injuries were not life-threatening, but no other details were immediately known. The U.S. Air Force said in a statement that the explosion occurred at the facility managed by the Okinawa prefectural government at Kadena Air Base’s munitions storage area. It said no U.S. servicemembers were involved in the incident. The Self Defense Force’s joint staff said one of the devices suddenly exploded when the soldiers were inspecting it at the facility. The blast occurred when the soldiers were trying to remove rust, NHK television reported. The SDF said they are trying to confirm what caused the accident.
