(CNN) — Four Marines were killed Wednesday during a range maintenance operation at Camp Pendleton in California, the military said.
The names of the four Marines killed this week weren’t immediately released because their families were still being notified, the Marines said.
The four Marines were working in a range area used for live-fire exercises, but the deaths didn’t occur under such live fire, said a military spokesman who asked not to be identified while the matter is under investigation. The incident could have “very possibly” involved unexploded ordnance suddenly detonating, the spokesman said.
The range is known as Zulu Black, a Marine spokesman said.
The deaths are under investigation, the Marines said.
