Security forces exchange gunfire with shooter who opened fire twice at the gate of Joint Base San Antonio-Lackland

An individual shot at military members at an entrance to Joint Base San Antonio-Lackland early Saturday morning, a source familiar told NBC News.

A spokesperson for the base confirmed that there were no injuries or threats to the base.

San Antonio Police Sgt. Washington Moscoso said security personnel stated they heard several shots fired at them at the entrance gate to a training annex.

After the incident, more armed guards were added as a precaution. 

Just before 5 a.m., a sedan stopped outside the same gate and shots were fired again at the security personnel, Moscoso said.

Security personnel fired back at the individual, who got in the car and fled. There was an additional person in the car, and neither individuals appear to be affiliated with the military, the source familiar said.

Moscoso added that multiple Air Force personnel returned fire toward the suspect vehicle after additional security forces arrived on the scene.

“Upon investigation, evidence was located indicating shots were fired from the suspect vehicle’s location,” he said.

It’s not yet known how many rounds of fire were exchanged and what the motive was.

The base posted an alert on Facebook, saying the main gate at the Joint Base San Antonio-Lackland Chapman Training Annex would be closed “until further notice.” About three hours later, the base announced that the gate had reopened and normal operations had resumed.
