Fifteen Marines were hospitalized Wednesday after an amphibious vehicle caught fire during a training exercise at a Southern California base.
Eight of the Marines were medically evacuated to the Burn Center at the University of California San Diego Health. As of Wednesday evening, three were listed in critical condition and five were in serious condition.
Four other Marines were taken to the University of California Irvine Medical Center. The Marine Corps issued a statement on Twitter Wednesday night saying three of those Marines are in critical condition and one is in serious condition.
Another Marine at the Scripps Memorial Hospital in La Jolla was in stable condition and two others were treated for minor injuries at a Navy hospital at Camp Pendleton.
"Our thoughts and prayers are with the Marines and their families affected by this incident," a Marine Corps statement said.
The accident happened around 9:30 a.m. on a beach at Camp Pendleton Marine Corps base. Marine 1st Lt. Paul Gainey said Marines from the 1st Battalion, 1st Marine Regiment and 3rd Assault Amphibian Battalion were conducting a combat readiness evaluation as part of their training.
The incident is still under investigation.
