Man shoots himself at Houston airport after firing into air, witnesses and sources say

NBC's Pete Williams reports on the breaking news out of a Houston airport, where a man reportedly fired shots inside a terminal in a "planned suicide."

A man shot himself to death Thursday at the main Houston airport after firing into the air with an assault rifle, witnesses and law enforcement sources told NBC News.

The man had a suicide note in a backpack, the sources said. They said he was fired on by federal agents before producing a handgun and killing himself.

Authorities said the situation was contained and there was no public danger. It happened at Terminal B of George Bush Intercontinental Airport, outside of the secure area.

The Federal Aviation Administration stopped some flights arriving at the airport, one of the nation’s busiest. Police were turning cars away from the terminal.

The U.S. Immigration and Customs Enforcement said a homeland security agent was involved in the shooting but provided no other details.

Pete Williams and Miranda Leitsinger of NBC News contributed to this report.
