At least one U.S. marine is dead and eight other service members are missing after a training accident involving an amphibious assault vehicle (AAV) off the coast of southern California on Thursday.
The U.S. Marine Corps 1st Expeditionary Force tweeted early Friday morning that "search and rescue efforts are still underway" and that two people were injured during the incident.
The accident occurred during a 15th Marine Expeditionary Unit routine exercise near the island of San Clemente.
At approximately 5:45 a.m. on Thursday, Marines aboard an AAV reported they were taking on water. Of the 16 men who were inside the vehicle, only eight have been recovered.
"We are deeply saddened by this tragic incident," Col. Christopher Bronzi, the commanding officer of the 15th MEU, said. "I ask that you keep our Marines, Sailors, and their families in your prayers as we continue our search."
The name of the Marine killed will not be revealed until next of kin have been notified. The incident is currently under investigation.
