WASHINGTON/SAN ANTONIO: Two people were killed Friday in a shooting on an air force base in Texas, authorities said, in what US media said appeared to be a murder-suicide.

The fatal shooting of two people appears to be a murder-suicide, authorities said.

Bexar County sheriff’s spokesman James Keith confirmed that two bodies were found inside a room at Joint Base San Antonio-Lackland. They were killed, he said without offering details about the circumstances of the incident.

The situation, which sparked a temporary lockdown at the facility, was now under control, another spokesperson, Rosanne Hughes said. The Air Force Times, citing initial internal Pentagon communications, said an airman shot the commanding officer of a training squadron, before apparently turning the gun on himself.

Other US media cited local law enforcement as saying it was a murder-suicide.

Schools and daycare centers in the area were also placed on lockdown, according to a Facebook post from Joint Base San Antonio, which includes Lackland as well as other military bases in the area.

The deadliest shooting at a US military base took place in Fort Hood, Texas in 2009, when army psychiatrist Major Nidal Hasan killed 13 people and wounded more than 30 others before being overpowered by police.

It’s believed the shooter is among the dead, Keith said, adding that sheriff’s deputies and other law enforcement officers are continuing to search the building and nearby facilities.

Joint Base San Antonio-Lackland, the military’s largest joint base, is the home of Air Force basic training.

Fort Hood in Texas was the site of the deadliest shooting at a US military base, when 13 people were killed and 31 were injured in 2009.
