Fast-moving wildfires are affecting parts of the US.

Authorities say at least two dozen buildings have burned in the Cle Elum area of Washington state.

They include parts of The Chimpanzee Sanctuary Northwest, but so far no animals have been harmed.

Central Washington University has been asked to take in up to 100 people who have been forced to leave their homes.

Meanwhile, in California, around 7,000 acres have been consumed by fire.

Cal Fire say around 1,100 firefighters, seven air tankers, seven helicopters, 17 bulldozers and 134 fire engines have been used in their response to the flames.

The cause of both fires is unknown.
