More than 5,000 firefighters battled through the weekend to get at least a dozen big fires, at times fast-moving and erratic, under control across California.

The flames were fanned by record-breaking temperatures and shifting winds that kept firefighters racing from one place to another.

Reports said dozens of structures had been destroyed.

Southeast of Oroville in Butte County, the Wall fire spread to nearly nine square miles by late Sunday, forcing the evacuation of roughly 4,000 residents in its vicinity, officials said. It was about a quarter contained.
