A person has been killed in a wildfire burning in the Colorado foothills as numerous blazes torch large areas around the western United States. The blaze is one of several burning along the state's heavily-populated Front Range. Authorities said Wednesday that the body was found in one of five homes that burned in the fire near Lyons, Colorado. A second fire burning southwest of Denver has triggered evacuation orders for 575 homes. Around the U.S., nearly 28,000 firefighters are battling large fires that have burned almost 7,000 square miles of land to date this year.
