A massive commercial building fire broke out in South Gate, California, on Sunday, sending thick black smoke across parts of the Los Angeles area.
The LA County Fire Department reported that crews were in defensive mode at the scene of a one-story building with smoke and fire showing.
Videos circulating online showed dense black smoke pouring into the sky, but officials have not yet released details about what sparked the fire or the extent of the damage.
No injuries have been reported, and authorities have not confirmed whether nearby businesses were evacuated as a precaution.
Firefighters remain at the scene working to contain the blaze, which comes as officials continue responding to a separate chemical leak crisis in Garden Grove, about 28 miles away.
