All five Marines on board an Osprey aircraft died after it crashed during a training mission on June 8 near Glamis, California, the United States Marine Corps said in a statement on June 9.
The five died “following an aviation mishap,” the statement from the 3rd Marine Aircraft Wing, an aviation squadron based in San Diego, said in the statement.
Military firefighters and the Imperial County Fire Department responded to the crash, which was reported at 12:25 p.m. local time, according to NBC News.
The circumstances that led to the crash are not clear.
The Marines said that equipment efforts have begun and that the investigation was ongoing.
“Contrary to initial social media reports, there was no nuclear material on board the aircraft,” the Marines said in an earlier statement.
The U.S. Marine Corps has not yet identified the victims.
“As a matter of policy, identities of deceased service members are not released until 24-hours after all next-of-kin notifications have been completed,” the statement said.
