The Los Angeles Fire Department (LAFD) tweeted that the blaze inside the one-story commercial building was reported at 6.26 p.m. on Saturday, reports Xinhua news agency.
“As firefighters were making their entry in and finding the seat of the fire, there was a significant explosion,” LAFD Captain Erik Scott told a news briefing.
The explosion caused fires at several buildings.
“Over 230 firefighters are responding. Firefighters have moved to a defensive posture for fire attack, and a medical branch has been created for treating and transporting injured firefighters,” the LAFD said in a fire update later.
