Tens of thousands of people have been evacuated and hundreds of homes have been destroyed as wildfires spread through the US state of Colorado.
The fast-moving fires are burning in Boulder County, north of Denver, and officials say deaths and injuries are likely as the blazes spread further.
Some 30,000 people in the towns of Louisville and Superior were told to leave their homes on Thursday.
Meanwhile, a state of emergency has been declared by Governor Jared Polis.
“This fire is not so much a question of resources,” he told a press conference. “This fire is a force of nature.”
“We hope that the winds die down, that the weather changes,” he added. “But for those who are directly affected, know that you don’t stand alone.”
