LOS ANGELES - Shots were fired Friday morning inside Los Angeles International Airport and law enforcement officials say the gunman was Paul Ciancia, 23, of New Jersey.
According to multiple news sources, one TSA officer was shot and killed and at least six others were injured by Ciancia, who had a semi-automatic weapon.
Ciancia was shot and is in custody. There's no word yet on his condition.
A law enforcement official who was not authorized to speak publicly said the gunman was wearing fatigues and carrying a bag containing a hand-written rant about killing Transportation Safety Administration workers and police. The official requested anonymity because he was not authorized to speak publicly.
At a news conference, Chief of Airport Police Patrick Gannon said that around 9:20 (local time) Friday morning, Ciancia walked into Terminal 3, pulled an assault rifle out of a bag and opened fire.
Gannon said the gunman went to the screening area and continued firing. He made his way past the screeners and "into the airport itself." He was tracked down down by officers and shot. Gannon said he was taken into custody and transported to a hospital.
Gannon said investigators believe the shooter acted alone.
A total of seven patients were treated and six hospitalized. It was not clear if the gunman is included in that number.
Chief Gannon repeatedly said he could not confirm if a TSA agent was killed.
Travelers described the scene as chaotic following the shooting. Hundreds were evacuated from Terminal Three.
Witness Brian Keech said he heard "about a dozen gunshots" from inside the security gate at Terminal 3.
Helicopter video showed dozens of emergency units.
Other television images showed two people being wheeled away by firefighters. Triage stations also were seen.
A ground stop for arrivals at LAX was ordered by the FAA.
As a result of the shooting at LAX, Tampa International Airport has increased the number of TSA officers stationed at checkpoints.
