Multiple fire departments were battling a three-alarm fire at a single-story mall in Chula Vista, San Diego, on Tuesday night.

The fire broke out at Santa's Toys store inside the mall on Palomar Street and by the time firefighters arrived at the scene, the flames had already reached the roof.

Dozens of fighters were at the scene tackling the blaze. A San Diego Gas and Electric crew were also called to the scene. The cause behind the blaze was unknown. No other information was available at the moment.

This is a developing story.
