More than 65,000 people have evacuated their homes in the northwestern U.S. state of Washington as multiple wildfires continue to tear across the region, leaving firefighters battling several fast-moving blazes with no containment.

However, the fires near Spokane and Stevens counties had burned 8,026 acres (3,248 hectares) since igniting on Saturday and remained 0% contained, according to InciWeb, the U.S. interagency wildfire information system.
Separate reports indicated aerial surveys found between 700 and 1,110 structures had been lost since the fires broke out over the weekend, while firefighters used cooler temperatures, higher humidity and dense smoke to make significant progress on two of the three Spokane-area fires. No injuries had been reported.
Elsewhere in the state, the Sinlahekin Fire has expanded to 85,000 acres after being sparked by lightning on July 26. More than 820 personnel are fighting the blaze, which also remains uncontained.
