Arizona mourning 19 firefighters killed in wildfire

At least 19 US firefighters have been killed battling a wildfire in central Arizona, local officials say.

They died while fighting the blaze threatening the town of Yarnell, about 80 miles (130km) north-west of Phoenix.

The fire was started by lightning on Friday and has spread rapidly to 2,000 acres (800 ha) amid high heat, low humidity and strong winds.
