(CBS/AP) A man fired two shots in the air with an assault rifle before shooting himself Thursday at north Houston's Bush Intercontinental Airport, CBS affiliate KHOU reports.

The Houston Police Department and witnesses told the station a man walked into Terminal B and fired at least two shots into the air with an AR-15 rifle.

According to police, a call came in at 1:35 p.m. about  a "discharge of firearms" around the ticket counter area, which is pre-security. 

An air marshal fired at the suspect, but missed, reports the station. The man then shot himself with a pistol, according to police.

Police told KHOU the man did not survive.

The U.S. Federal Aviation Administration reports that there is a ground stop that was initiated by one airline for flights scheduled to arrive at Terminal B.

Federal authorities say the incident is being investigated by local police.
