Seven Marines were killed when two helicopters collided during a routine training exercise in Yuma, Ariz., the Marine Corps announced Thursday.
According to a statement, the crash occurred around 8 p.m. Wednesday in a remote portion of the Yuma Training Range Complex. The two aircrafts in the accident were the AH-1W “Cobra” and the UH-1Y “Huey.”
The Yuma air station said identities of the seven Marines killed will be withheld until their families have been notified, and an investigation of the incident is ongoing.
