Military officials said, four Marines were killed Wednesday during a range maintenance operation at Camp Pendleton in California. The incident was the deadliest for Pendleton since seven Marines were killed in a February 2012 midair collision between helicopters along the Arizona-California border, said a military spokesman. A military source 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. The matter is under investigation and the names of the four Marines killed this week weren't immediately released. Their families were still being notified. less
