Two US marines were killed when an attack helicopter crashed during training at a California military base on Monday, a spokesman said.
The AH-1W Cobra went down on a training ground at Camp Pendleton south of Los Angeles, said Steven Posy, a spokesman for the 3rd Marine Aircraft Wing based there.
Both occupants died at the scene of the crash, which ignited a small brush fire, he added. The cause of the accident was under investigation.
