A wildfire burning unchecked in Washington state has destroyed at least 23 homes and three commercial buildings near the eastern foothills of the Cascades, state police and emergency management officials said on Monday.

The so-called Sleepy Hollow fire has scorched an estimated 3,000 acres (1,200 hectares) of rolling grasslands and brush in and around Wenatchee in central Washington since it erupted on Sunday, said state patrol spokesman Darren Wright.

A couple of firefighters suffered minor injuries, Wright said.
