At least two celebrities were at LAX today, according to Twitter.
"At #lax," Franco, who also posted a photo of himself from inside an aircraft, wrote. "Some s** tbag shot up the place."
Minutes later, Nick Jonas tweeted that he, too, was at LAX.
"Landed at LAX to the news that there was a shooting in the terminal my plane was supposed to deplane at," he wrote. "Currently waiting on the plane in a remote parking area. I am safe. Praying for the victims of this shooting."
Law enforcement has confirmed that a TSA officer was killed in today's shooting, and that two others were injured. The alleged shooter is in custody, and police were trying to determine whether there could been a second gunman.
