An investigation into the deaths of 19 firefighters in Arizona on 30 June has found that inadequate communication played a role in their fate.

The dead men, members of an elite unit called the Granite Mountain Hotshots, were killed as they battled a wildfire near the town of Yarnell.

The report authors describe radio communications as "challenging throughout the incident".
