A Camp Lejeune Marine died Thursday during a training exercise near the North Carolina base, Marine Corps officials said Friday.

The Marine was a member of the 24th Marine Expeditionary Unit and was participating in a nighttime training exercise in Carteret County, just east of Camp Lejeune in coastal North Carolina, according to the II Marine Expeditionary Force. The Marine’s name was not released Friday, pending the Defense Department’s next-of-kin notification process, service officials said.

The deadly incident was under investigation Friday, and Marine officials declined to provide any further details about it.

The 24th MEU is a unit built of Marine Corps air, ground and logistics forces that can deploy around the globe aboard Navy ships. The unit is part of Camp Lejeune’s II MEF.

Marines from the 24th MEU have spent recent days training with the Navy’s Wasp Amphibious Ready Group in the western Atlantic Ocean, including off North Carolina’s coast, according to recent Marine and Navy social media posts.
