At least three people were injured when a gunman opened fire at the Pearl Harbor Naval Shipyard in Hawaii on Wednesday, a Navy spokesperson said.
The shooting at the base was reported to authorities at about 2:30 p.m. local time, causing the facility to be placed on lockdown, the spokesperson added.
“Due to the ongoing security incident access and gates to joint base Pearl Harbor Hickam are closed,” Jackey Smith, of commander Navy Region Hawaii Public Affairs said.
One witness said he was at his desk said he saw the shooter wearing a naval uniform, according to Hawaii News Now.
“I kind of recognize that as gunshots,” the witness told the local outlet.
“I looked out in time to see the shooter, who I assume was a sailor because he was in uniform … shoot himself.”
Civilians were among those injured in the shooting, the outlet reported, citing law-enforcement sources.
The shooting was contained and the FBI was investigating, a spokesperson said.
