Nineteen firefighters are confirmed dead after battling a blaze in central Arizona, according to a spokesman with the Prescott Fire Department.
The 19 members were part of a "hotshot" crew, who were working on a fire line to contain the fire.
The exact cause of death is unknown at this time.
The wildfire broke out Friday northwest of Phoenix, and the fire is nearly 2,000 acres in size.
Subdivions near Yarnell were evacuated as this fire grew quickly, from 300 acres early Sunday morning to about 1,000 acres by noon.
"It was a hand crew, a hot-shot crew. And in normal circumstances when you're digging fire line, you make sure you have a good escape route, and you have a safety zone set up, and evidently their safety zone wasn't big enough, and, you know, the fire just overtook them," said Art Morrison of the Arizona Forestry Commission.
Republican Congressman Paul Gosar of Arizona issued a statement in response to the deadly fire.
It reads in part, "My heart weeps for those who lost their lives and were affected by today's Yarnell Hill fire. My thoughts and prayers go out to the families who have lost so much and the first responders battling this difficult situation."
