A U.S. Marine Corps helicopter crashed Tuesday — killing its four crew members — during exercises along the U.S.-Mexico border near Plaster City, Calif., military officials said.
“We are currently still responding to what we have confirmed as a single helicopter incident,” said a Facebook post from the nearby Naval Air Facility El Centro.
The naval facility sent fire and security units as well as other helicopters to the scene of the crash, KYMA-TV reported.
