A very disturbing incident just took place at Houston's Bush Intercontinental Airport.
According to KHOU, witnesses say a suspect walked into the ticket area in Terminal B, and fired at least two shots into the air with an AR-15 rifle.
An air marshall then fired at the suspect, and the suspect pulled out a pistol and killed himself.
The suspect was taken to the hospital, but multiple sources are reporting he has been confirmed dead.
Twitter user Greg Newburn took the following video of the aftermath.
