One Marine died, two service members were injured and eight others were missing after an accident involving an amphibious vehicle off the coast of Southern California on Thursday, the authorities said.
Search and rescue efforts were continuing early on Friday, the First Marine Expeditionary Force said in a statement on Twitter. The service members were assigned to the 15th Marine Expeditionary Unit at Camp Pendleton, in the San Diego area.
The Marine, whose name was not released, was pronounced dead at the Scripps Memorial Hospital La Jolla, a news release from the Marine unit said. One of the injured Marines was in critical condition and the other was in stable condition, it said.
There had been 15 Marines and one sailor inside the vehicle, the force said. Officials did not provide details about what happened in the accident, except that it involved an amphibious assault vehicle.
The Navy and the Coast Guard were assisting in the search, the force said.
“We are deeply saddened by this tragic incident,” Col. Christopher Bronzi, a commanding officer, said in a statement. “I ask that you keep our Marines, sailors and their families in your prayers as we continue our search.”
Camp Pendleton hosts the largest Marine base on the West Coast, and Marines often practice beach assaults there using the amphibious troop transport vehicles.
Marines have used the vehicles to move troops from the sea and land since the 1970s. In 2017, 15 Marines were wounded when an amphibious vehicle they were training in caught fire at Camp Pendleton.
