Fort Bragg officials say a civilian killed in an explosion at the North Carolina Army post was scavenging for scrap metal when he stepped on a round and it exploded.

Officials identified the man killed Friday as 47-year-old Ronnie Blue of Hamlet. They said Monday that another man was injured in the explosion. The blast occurred in an area that overlooks the range where soldiers practice firing artillery, tank shells and smaller weapons.

The post said the men were not Army employees.

Fort Bragg law enforcement officials are investigating.

The post is home to the Army's 82nd Airborne Division and Special Operations Command.
