Three people were killed Friday in what officials described as a “horrific incident” at a law enforcement training facility in Los Angeles, with multiple reports pointing to an accidental explosion.

The incident took place at the Biscailuz Training Center, used by the Los Angeles County Sheriff’s Department.

Attorney General Pam Bondi posted on X that there "appears to be a horrific incident that killed at least three at a law enforcement training facility" and that investigators were on-site "working to learn more."

California Governor Gavin Newsom's office said he had been briefed on "the reported explosion" and was "closely monitoring the situation."

Fox News and other media outlets reported that at least three sheriff's deputies were killed. According to the Los Angeles Times, which cited unnamed sources, the explosion occurred while the facility's bomb squad was moving explosives.

Officials have not confirmed the identities of the victims or the exact cause of the explosion. An investigation is ongoing.
