Three firefighters have been killed in the western United States while battling one of several major wildfires in the region.

It’s thought their vehicle was probably involved in an accident before being overcome by the flames. Another four were injured.

The blaze was threatening the town of Twisp in Washington state. The state governor Jay Inslee has called for a federal declaration of emergency which would free up resources to cover firefighting costs.

My heart breaks over the loss of life in the Twisp fire. We keep all firefighters in our prayers tonight http://t.co/NilDOy0Xj9 #wawildfire— Governor Jay Inslee (@GovInslee) 20 Août 2015


There have been moves to evacuate about 4,000 homes in Twisp and Winthrop, two towns in Washington’s Cascade mountains.

Strong winds are forecast to fan the flames further over the next two days.

All industrial forest activities including timbering and road construction are being halted in Washington’s affected areas.
