LOS ANGELES — An explosion rocked an area of East Los Angeles on Friday morning, killing at least three people.

The blast happened at a compound run by the Los Angeles County Sheriff’s Department, KABC reported.

KTTV reported that the location is home to the department’s Biscailuz Center Training Academy. It also holds the department’s special enforcement units and bomb squad, according to KABC.

Investigation continues

Update 2:46 p.m. ET, July 18: There are still a lot of questions and conflicting information in the hours after the blast.

The Associated Press reported that the explosion is being investigated as a possible training accident.

But Fox News said the blast was not part of a planned training exercise, and that it appears that it happened when deputies were moving ordnance.

CNN reported that it was unclear if the explosion happened during a training session or if they were handling evidence.

Homicide detectives are on the scene, as are the Los Angeles Fire Department’s arson team and members from the ATF.

There were conflicting reports about injuries, with The Los Angeles Times still reporting at 2:45 p.m. that one person was hurt, but Sheriff Robert Luna said that no additional people were injured in the blast, KTLA reported.

One injury reported

Updated 1:21 p.m. ET, July 18: At least one person was hurt in the explosion that left three deputies dead, according to The Los Angeles Times. The injured person was taken to an area hospital, but their condition was unknown.

The Associated Press reported that the sheriff’s office had not confirmed the deaths as of Friday afternoon, despite reports from several media outlets and a statement from Attorney General Pam Bondi.

The investigation into the cause of the explosion continues.

Staging set up at university

Update 1:17 p.m. ET, July 18: Cal State’s Los Angeles Campus is being used as a staging area.

The Los Angeles County Sheriff’s Department has taken over the campus’ parking lot 5.

While people are being told to avoid the area, the campus is safe, school officials wrote in a post on X.

ATF responds

Update 12:39 p.m. ET, July 18: The Los Angeles office of the Bureau of Alcohol, Tobacco, Firearms and Explosives is responding, according to a post on X.

DHS response

Update 12:30 p.m. ET, July 18: Homeland Security Secretary Kristi Noem said her department is working with state and federal law enforcement to respond and will give an update when one becomes available, KNBC reported.

The identities of the three people killed have not been released, according to Fox News.

Governor briefed, FBI responds to scene

Update 12:14 p.m. ET, July 18: The state of California “offered full state assistance,” the governor’s press office writing on X that Gov. Gavin Newsom has been briefed.

An employee told KTLA that they thought it was an earthquake because the explosion shook the ground but later found out what happened.

The FBI is responding to assist, the FBI’s Los Angeles Office told CNN.

Original report: The explosion happened just before 7:30 a.m., The Los Angeles Times reported. The area was evacuated.

It happened when bomb squad members were moving some explosives, and the Los Angeles Police Department bomb squad responded to make sure other explosives were made safe.

Several media outlets in the area are reporting that several people have been killed, but the sheriff’s office will only confirm that there was a “loud noise” and is working to find out what happened, KTLA, KABC and Fox News reported.

Attorney General Pam Bondi said on X that at least three people were killed.

KTLA and Fox News said those killed are county sheriff’s deputies, while KFOX said just before noon Eastern that it is unclear if they were deputies.

The blast was strong enough to blow out the windows of an SUV cruiser 25 yards away, the Times reported.
