At least seven U.S. Marines were killed and seven others were injured during a mortar firing exercise in Nevada, the Pentagon said today.
The Marines were all from the 2nd Marine Division based at Camp Lejeune, N.C., and were training at the Hawthorne Army Depot 140 miles southeast of Reno, Nev., when a mortar exploded shortly before 10 p.m. Monday.
The injured were taken to area hospitals, according to a statement from the Marines.
Several defense officials say this incident did not appear to involve a round landing on the troops.
