In a tense encounter early Saturday morning, U.S. Air Force security guards at Joint Base San Antonio-Lackland engaged in a firefight with an individual who opened fire at the entrance of the base. According to base officials, the incident occurred at approximately 4:30 a.m. local time when a suspicious dark sedan approached the main entry gate and began shooting towards it.

The suspect reportedly attempted to fire again, prompting a service member on guard duty to respond by returning fire. Fortunately, no injuries were reported during the exchange of gunfire, as confirmed by public affairs chief Stefanie Antosh.

Details surrounding the incident still remain unclear. Officials have not disclosed the exact number of rounds fired, the motive behind the attack, or the number of shooters involved. However, Antosh stated that there is currently no evidence to suggest that the suspect had any ties to the military.

Although the entrance was temporarily closed for investigation purposes, the incident did not result in a lockdown of the base. Operations returned to normal after 10 a.m., according to local CBS News affiliate KENS5.

San Antonio police also arrived at the scene, assisting with evidence collection. At present, no arrests have been made in connection with the incident.

Joint Base San Antonio-Lackland is home to a significant military presence, housing over 24,000 active duty members and 10,000 Department of Defense civilians. The base encompasses several important units, including the 37th Training Wing, 149th Fighter Wing, and the Air Force Intelligence, Surveillance and Reconnaissance Agency.

As investigations continue, authorities are striving to determine the motives and circumstances surrounding the suspect's attack.
