A massive law enforcement response is underway Monday at San Antonio International Airport following reports of a possible active shooter situation.

According to preliminary information, numerous police units and emergency responders rushed to the airport after authorities received reports of a potential armed threat on airport property. Witnesses described seeing heavily armed officers, emergency vehicles, and increased security activity throughout the area as officials worked to assess the situation.

Travelers and residents have been urged to stay away from the airport and surrounding roads while law enforcement secures the scene and conducts an active investigation.

Videos and social media posts from the area showed a heavy police presence outside portions of the airport, with some travelers reportedly being redirected or temporarily prevented from entering certain sections of the facility.

At this time, authorities have not confirmed whether shots were fired, whether any injuries have occurred, or if any suspects are in custody.

The situation remains rapidly developing, and officials are expected to release additional information as it becomes available.

Anyone currently near the airport is being urged to follow instructions from law enforcement and airport personnel until the scene is fully secured.
