Three wildland firefighters died while fighting the Knowles and Gore fires along the Colorado-Utah border on Saturday. Two crew members were also injured in the line of duty and were taken to a hospital.

The U.S. Wildland Fire Service made the announcement on Facebook on Sunday. The firefighters were part of an interagency response to the Knowles and Gore fires.

“The U.S. Wildland Fire Service stands united with the USA Forest Service in grief and in our unwavering support for the loved ones left behind,” the post reads. “Their bravery, dedication, and sacrifice will never be forgotten.”

More details will be shared when they are able to be released, according to the U.S. Wildland Fire Service.

Gov. Polis verbally declared a disaster emergency in response to the fires on Saturday. According to a press release from his office, the Jones, Snyder Mesa and Knowles Fires have combined and are now the Snyder Mesa Fire. The Snyder Mesa Fire is now estimated to be more than 28,000 acres total. The emergency declaration includes the authorization of the Colorado National Guard to support response efforts.
