A fire quickly consumed and destroyed a home in San Francisco's Sunset District, and the fire reportedly began with or included an explosion that shattered windows in neighboring homes.

The San Francisco Fire Department responded to the three-alarm blaze around 9:30 a.m. Thursday at 1749 22nd Avenue, near Noriega Street. As KTVU reports, "By 10:25, the home was a charred shell."

Photos from the scene show the house, in a row of similar houses, fully engulfed in flames and then destroyed. And KTVU reports that multiple nearby homes were evacuated.

The SFFD said in a tweet that one person was injured in the fire and was being treated for burns.

At least two other homes, on either side of the fire, appear to have suffered damage.

Neighbors told KTVU that they heard an explosion, but that has not been further explained.

Supervisor Joel Engardio tweeted from the scene that there was a "possible gas explosion" at the home, and there was a "possible fatality."

Writing on Twitter, local resident Ted Goldberg says, "We heard and felt what sounded like an explosion moments before this fire in San Francisco's Sunset district started sending out smoke."

Update: The Chronicle reports, via Sup. Engardio, that PG&E is on the scene and assisting with the investigation into the cause of the fire.

One injured resident reportedly suffered "serious" burns, and a firefighter was injured in the blaze as well. Engardio says that talk of a possible fatality is "speculation because firefighters can't get in to search the debris pile yet."
