LAS VEGAS (Reuters) - A mortar explosion at a U.S. Army munitions depot in Nevada killed seven Marines from Camp Lejeune, North Carolina, and injured seven other service members during a live-fire training exercise, U.S. military officials said on Tuesday.
A Marine Corps official said a 60mm mortar round exploded prematurely Monday night during training at the Hawthorne Army Depot in western Nevada. The cause was under investigation.
