Sandy Fire spreads in California

More than 17,000 people have been ordered to evacuate as a fast-moving brush fire threatens suburban homes in Southern California.

The wind-driven Sandy Fire has consumed thousands of acres with containment currently reported at only 15%.

One homeowner in Simi Valley credited a doorbell camera alert with helping save his wife's life as flames engulfed their property.

Firefighters are battling the blaze in extreme heat, with air quality alerts issued for much of the region due to heavy smoke and ozone pollution.

Officials warn that the fire remains a significant threat to infrastructure and that evacuation orders may be expanded if wind conditions deteriorate.
