Update - 4:20PM

Officials say a TSA employee is dead and two other people have been wounded in a shooting today at Los Angeles International Airport.

They say a man with a semi-automatic weapon opened fire near a security checkpoint. The gunman was apparently wounded in an exchange of gunfire with officers and is in custody.

A spokesman for a government employees union confirms that a TSA officer was killed.

The airport's police chief says the gunman pulled the rifle from a bag this morning and began firing inside Terminal 3. He says the shooter went to the security screening area and fired more shots, before moving into the secure area of the terminal.

There, he says, officers exchanged fire with the gunman and apprehended him.

Air traffic was affected nationwide, as the Federal Aviation Administration grounded flights that had not yet departed for Los Angeles.

The Los Angeles Fire Department says six people were taken to a hospital. It's not clear whether the gunshot victims were among them.
