At least 192 structures were destroyed by a fan-flamed wildfire that quickly spread to more than 20,000 acres in Ventura County, officials announced in a press conference Monday.

Nearly a week after the destructive Mountain Fire destroyed more than a hundred buildings and torched tens of thousands of acres of brush in Ventura County, firefighters are defending their response to the blaze as some residents return to their burnt homes.

The Mountain fire has burned more than 20,000 acres and destroyed 134 structures in Ventura County. It was about 26% contained as of Sunday morning.
