Firefighters battle California’s seventh largest wildfire on record as thousands under threat

The Park fire has more than doubled in size in 24-hour span to burn 350,000 acres and stretches over four counties

Thousands of firefighters continued to battle the Park fire in northern California which, propelled by extreme fire weather conditions, has become the state's seventh-largest on record after burning for less than a week.

The Park fire, about 90 miles (144km) north of the state capital of Sacramento, had more than doubled in size in a 24-hour span to burn upwards of 350,000 acres (141640 hectares) - an area about the size of Los Angeles - and stretched over four counties: Butte, Plumas, Shasta and Tehama, according to the California department of forestry and fire protection, or Cal Fire.
