A power company has started cutting electricity to around 800,000 homes, businesses and other locations in Northern California, in an attempt to prevent wildfires.
Large swathes of the San Francisco Bay Area – though not the city itself – are expected to be affected.
The region’s utility company, Pacific Gas and Electric (PG&E), has warned the shut down could last several days.
The move has drawn anger from some residents.
