At least three people were injured Saturday following an explosion and fire in an industrial area of downtown, fire officials said.

The explosion occurred in a building in the 700 block of South Kohler Street around noon, sending a plume of black smoke several hundred feet in the air, according to the Los Angeles Fire Department. The building was described as 50-feet-by-100-feet.

The condition of those injured was not immediately available.

More than 130 firefighters responded to the scene.
