[CN: links cannot be guaranteed to be safe or image-free. Discussion of gun violence]

Per news reports, there has been a shooting at Lackland Air Force Base in San Antonio, Texas. Local news is reporting two dead, although few details are confirmed. As of 10 AM local time, the base is still on lockdown:

The active shooter forced the base to lock down before 9 a.m. while law enforcement swarmed the Medina Annex.

Bexar County Sheriff's Office spokesman James Keith said the bodies of two people were found in a room on the base, which is located in southwestern Bexar County and remained locked down as of 10 a.m. with "deputies still inside," according to officials.

The identities of the victims have not been released, but according to "initial internal Pentagon communications obtained by the Air Force Times, the commanding officer of the 331st K-9 Training Squadron at the base was shot by an airman."

Several law enforcement agencies, including the FBI, responded to the base, which last reported a population of just under 10,000 people. Schools and other military installations in the area were also shut down.

UPDATE as of noon ET:

NBC news is reporting that there is no indication there is a relation to "terrorism." (NB: I suspect they mean terrorism related to IS or other overseas extremists, since our media seldom labels homegrown Christian-inspired and/or misogynistic violence as terrorism.) A graduation from an Air Force training program had been scheduled for that morning.

Update #2 According to a news report from WHNT News in Huntsville AL, the lockdown has been lifted. Two weapons were found. Authorities are reporting that both victims were men. The training squadron may have been misidentified. No other news about the victims will be released until military policy about next of kins has been followed.

Update #3 The Air Force has announced that no trainees or family members were harmed in the incident.

This being reported as an apparent murder-suicide.

Update #4 As of Friday afternoon, the Air Force Times seems to have the most up to date account. No information about the men's relationship will be released yet is being officially released, despite earlier reports than an airman shot his commanding officer. The Office of Special Investigations' 11th Field Investigations Squadron at Joint Base San Antonio is investigating. A tweet from the local sherriff's office says the investigation is now out of their hands.

My condolences and sympathies to the families of those involved, and to everyone anxious about friends and relatives at the base.
