Explosion at a US air base in southern Japan injures 4 Japanese soldiers

TOKYO: An explosion at a storage site for unexploded ordnance at a US 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.
