SAN DIEGO (AP) - Four Marines have been killed during an operation to clear a range of unexploded ordnance at Southern California's Camp Pendleton.
A Marine official with knowledge of the incident tells The Associated Press that the four were clearing the range of unexploded ordnance when the accident occurred at 11 a.m. Wednesday at the San Diego County coastal base. The official spoke on condition of anonymity because he wasn't authorized to speak publicly.
The identities of the dead were withheld pending notification of relatives.
Base officials released no details on the accident. They say authorities are investigating the cause.
The deaths come about eight months after a mortar explosion killed seven Marines during a live-fire training exercise in Nevada. A military investigation determined human error was to blame for that accident.
