Governor says containing Colorado wildfire is 'tough'

More than 800 firefighters are battling to contain a wildfire that is burning out of control on the outskirts of the town of Colorado Springs, in the US state of Colorado, prompting the evacuation of 32,000 people.

The governor of Colorado, John Hickenlooper, said the situation was "tough", but added that "we are not going to quit" efforts to contain the blaze.

Extreme fire warnings are in place in several western states as record-setting heat and prolonged drought has triggered wildfires across the region.
