Extreme wildfire in California prompts multiple mandatory evacuations

Dubbed Fawn Fire, the fire started some 19 km north of Redding city on Wednesday night, and raged through Thursday afternoon, Xinhua news agency quoted the California Department of Forestry and Fire Protection (Cal Fire) as saying.

"I would call it extreme," Cal Fire spokesperson Robert Foxworthy said on Thursday afternoon.

"There are quite a few mandatory evacuations, and they're coming out continuously. I would advise people to look at the latest information from the sheriff's department," Foxworthy added.

The Fawn Fire has forced 4,000 people to evacuate and "affected" 30,000, the Shasta County Sheriff's Office said in a tweet without elaboration.

Cal Fire also announced on Thursday that a 30-year-old woman, Alexandra Souverneva, was arrested on fire-related charges in the area where the blaze started.

Cal Fire said that it would submit the case to the Shasta County District Attorney's Office, recommending Souverneva be charged with "arson to wildland".
