Multiple explosions and a large fire at a U.S. Army depot lit up the night sky in a Tokyo suburb early Monday. No injuries were reported. The blast happened after midnight at the Sagami General Depot in Sagamihara, a city about 25 miles (40 kilometers) southwest of Tokyo, said Navy Commander Bill Urban, a Pentagon press officer. The building that exploded was storing compressed nitrogen, oxygen, Freon and air, a statement issued by the U.S. Army Japan said. Photos taken after daybreak and released by the Army show dozens of gray canisters lying on the floor, and what looks like mangled storage racks. The walls of the one-story, concrete building remain intact, but the windows and doors are damaged and about half of the roof collapsed, the Army said. There are no indications of injuries.
