Deadly wildfire in Arizona

The Yarnell Hill Fire burns through the town of Yarnell, Ariz., June 30, 2013.

Triple-digit heat and 45 mile-per-hour wind gusts fueled an out-of-control blaze in a forest northwest of Phoenix, overtaking and killing 19 members of an elite fire crew.

It was the deadliest wildfire involving firefighters in the U.S. in 80 years.

On June 30, 2013, a crew of "hotshot" firefighters was forced to deploy their emergency fire shelters meant to shield them from flames and heat, when they were caught by the fast-moving wildfire near Yarnell, state forestry spokesperson Art Morrison told The Associated Press.

Nineteen firefighters died. At least eight firefighters suffered injuries and were taken to a local hospital.
