Fire crews have knocked down a brush fire that burned through a canyon near a community of Linda Vista homes, San Diego Fire-Rescue (SDFD) Capt. Amador said.

The fire started just after 5 p.m. Monday at Genesee Avenue and Osler Street, sending thick white smoke through the air. Crews knocked it out at approximately 6:10 p.m.

The flames scorched nearly an acre of land near Linda Vista Community Park, Amador said. The blaze moved at a slow rate of speed.

Crews are expected to work throughout the night on mopping up the fire.

It is unclear what started the fire, Amador said. No injuries have been reported and no evacuations were issued.

There is no word on the cause of the fire
