A mortar exploded during a training exercise Monday night, killing seven and injuring seven U.S. Marines at the Hawthorne Army Depot in western Nevada, according to military officials.
Hawthorne Army Depot is a storage facility and special forces training location that offers “realistic simulation of the situation in Afghanistan.”
Maj. Gen. Raymond C. Fox issued a statement about the incident Tuesday:
“We send our prayers and condolences to the families of Marines involved in this tragic incident. We remain focused on ensuring that they are supported through this difficult time … We mourn their loss, and it is with heavy hearts we remember their courage and sacrifice.”
The death toll was initially six Marines, but rose to seven Tuesday morning.
