Officials are investigating the motive behind the deadly shooting at Naval Air Station Pensacola by a Saudi aviator in training.

The shooter pulled out a handgun in a classroom at the Navy base and opened fire, killing three people and injuring eight others before a deputy fatally shot him, authorities said.

While the FBI has not yet confirmed whether or not it's investigating terrorism as a motive for the attack, Pensacola's congressional representatives have characterized the incident as an "act or terrorism."

The shooting happened just two days after a U.S. Navy sailor shot three people and then killed himself at Pearl Harbor.
