A few famous faces were among the passengers present at Los Angeles International Airport (LAX) on Friday after a gunman opened fire at security officials inside a terminal.

At about 9:30 a.m. local time, an unidentified shooter targeted a Transport Security Administration (TSA) official at a Terminal 3 checkpoint.

Police evacuated the building and surrounding areas, and authorities grounded all flights while they sought the suspect, who was shot and reportedly killed shortly after officers conducted an airport-wide manhunt.

Actor James Franco was sitting on a plane on a runway during the commotion, suggesting he was grounded during the event.

He posted a photo on Instagram with the caption: "At lax Some s**tbag shot up the place."

Singer Nick Jonas was also at LAX during the shooting. He tweeted: "Landed at LAX to the news that there was a shooting in the terminal my plane was supposed to deplane at. Currently waiting on the plane in a remote parking area. I am safe. Praying for the victims of this shooting."

Meanwhile, "Mythbusters" stars Grant Imahara and Tory Belleci were among those evacuated from Terminal 3. The Discovery Channel issued the following statement: "'Mythbusters' Grant Imahara and Tory Belleci were present in Terminal 3 at Los Angeles International Airport at the time of today's shooting incident.
