Arizona fire department 'devastated' by deaths

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 spread rapidly amid high heat, low humidity and strong winds. At least 200 homes were burned.

Prescott fire chief Dan Fraijo said "the entire state is being devastated by the magnitude of this incident".
