An elite team of 19 firefighters died Sunday while trying to protect themselves under fire-resistant shields from a fast-moving wildfire in Yarnell, Ariz., according to officials.
Authorities believe the wildfire began in Yarnell, about 90 miles northwest of Phoenix, Friday after a lightning strike.
The 19 deaths is the greatest loss of life for firefighters in a wildfire since 1933, according to the National Fire Protection Association.
Eighteen of the victims were from the Prescott Granite Mountain Hotshots, fire officials said. It's unclear where the other victim was based.
The fire has scroched more than 8,000 acres.
Roses hang at a makeshift memorial for the fallen firefighters.
