A US sailor fatally shot two people and wounded a third at the Pearl Harbor Naval Shipyard in Hawaii on Wednesday before taking his own life, a senior Navy officer said.
The base was locked down for more than an hour after the shooting, according to a statement issued by the facility, while Navy officials said they were investigating what prompted the attack.
"I can confirm that there were three shooting victims. We have confirmed that two are deceased, one is in stable condition in a local hospital," said Rear Admiral Robert Chadwick.
He added that the shooter -- "tentatively" identified as a sailor assigned to the USS Columbia, a Los Angeles-class attack submarine -- had also died after "an apparent self-inflicted gunshot wound."
In July 2015, Mohammad Youssuf Abdulazeez carried out an attack at two military installations in the US state of Tennessee that killed four Marines and a sailor, with the FBI concluding that the violence was inspired by a "foreign terrorist group."
