It gave no more information immediately about Ciancia, who killed an airport security agent and injured several others on Friday, and who had "strong anti-government views," according to a report.

"The suspect in today's LAX shooting has been identified as Paul Anthony Ciancia, 23, a resident of Los Angeles," said an FBI statement on Friday. The gunman opened fire with an assault rifle in Terminal 3 of the airport, shooting his way through a Transportation Security Administration (TSA) security checkpoint.

He proceeded into the main part of the terminal, shooting in other locations before being detained after a gunfight with police. Reports said he was in critical condition in hospital. A report suggested Ciancia may have had some link to the Transportation Safety Administration (TSA), and targeted TSA agents as his victims.

Earlier reports said he may have been an off-duty TSA employee, but this was not confirmed. A new press conference by the FBI, as well as LA law enforcement agencies, was due to be held at 4:00 pm (2300 GMT), the FBI statement said.
