Three U.S. Forest Service firefighters were killed Wednesday while battling a massive wildfire in eastern Washington state. Gov. Jay Inslee said the men became trapped while battling a fire near the town of Twisp, while as many as four other firefighters were injured. The blaze quickly spread across 1,500 acres Wednesday and about 230 firefighters and 20 aircraft, with support from Canadian firefighters, managed to contain about 20 percent of it. The inferno is one of 15 large wildfires that have burned more than 235,000 acres across Washington. Also Wednesday, Inslee requested a federal emergency declaration in order to get additional resources and support to cover the costs. About 200 soldiers have been deployed from Joint Base Lewis-McChord near Tacoma to join the more than 26,000 firefighters battling the fires.
