WASHINGTON, Dec. 6 (Xinhua) -- At least three people were killed and seven others were injured after a shooter opened fire inside a classroom building at Naval Air Station Pensacola in Florida early Friday morning, authorities said.
Two deputies engaged the shooter, whom was fatally shot, Sheriff of Escambia County David Morgan told a press conference. The two officers were also shot but are expected to recover after receiving treatment.
Eight others suffering from gunshot wounds were transported to a local hospital, where one of them died, officials said.
Morgan said they received call about an active shooter at 7:51 a.m. local time.
"Walking through the crime scene was like being on the set of a movie," the sheriff told reporters, while refusing to provide additional information, citing an ongoing investigation.
A U.S. Navy spokesperson said in a statement that they "will continue to work closely with law enforcement agencies."
The names of the victims will not be released until the next kin have been notified, Naval Air Station Pensacola wrote on one of its Facebook posts.
The base's security and the Naval Criminal Investigative Service are currently investigating.
Located in Florida's northwest corner, the facility, which employs more than 16,000 military and 7,400 civilian personnel, is closed for the remainder of the day.
President Donald Trump has been briefed on the shooting and is monitoring the situation, said White House deputy press secretary Judd Deere in a statement.
Vice President Mike Pence tweeted he's "saddened to hear of the horrible shooting."
Mayor of Pensacola Grover Robinson called it a "tragic day" for the city.
It was the second shooting at a U.S. military facility this week.
A shooting on Wednesday afternoon in Pearl Harbor Naval Shipyard in Hawaii left three dead, including the gunman.
