RENO, Nev. — Seven Marines were killed as the result of an explosion during a Marine Corps training exercise at Hawthorne Army Depot in western Nevada, the Marine Corps said Tuesday.
The cause of the incident is under investigation, the Marines said. A representative of Nevada’s Regional Emergency Medical Services Authority said four medical helicopters were sent to transport patients to hospitals. Very little was immediately known about what caused the explosion.
Lt. Col. Craig Short, Hawthorne’s deputy commander, said a traffic accident at the facility around 10 p.m. was related to the blast, but he didn’t explain what the connection was. Senate Majority Leader Harry Reid, who represents Nevada, called it “quite a big explosion” and said the area of the blast is cordoned off as details emerge.
