Shots were fired near a ticket counter at Houston's largest airport on Thursday, and at least one person was critically injured, a Houston police spokesman said.
Houston police responded to a call that there had been a "discharge of firearms" at 1:35 p.m. at the Bush Intercontinental Airport in Houston, a police source told MyFoxHouston.com.
KHOU.com reports that a man fatally shot himself with an AR-15 near a security checkpoint. Reports indicate that a body was found in the lobby of Terminal B of the airport.
The Houston Police Department told KHOU.com that an air marshal fired at the suspect, but missed. The man then pulled out a pistol and shot himself.
The FAA has issued a ground stop of arriving flights to Terminal B, but departing flights from Terminal B and flights in and out of the rest of the airport are unaffected.
Houston police spokesman John Cannon says one armed man has been transported to an area hospital with life-threatening injuries.
Dale Howard, of Tomball, was at the baggage handling area of the airport waiting for his sister to arrive on an incoming flight when he heard two shots fired from the floor above. A few seconds later, he said he heard three more shots.
"People were screaming. I knew exactly what it was -- gunfire," Howard said.
Police from an adjacent station rushed in, and Howard said he directed them to the floor above.
