More than 1,000 firefighters are making progress in containing a huge five-day-old wildfire in parched Colorado in the US.
Blazes are raging in several western US states, including Arizona, California, Utah and Wyoming.
As well as personnel on the ground, ten planes and 14 helicopters are being used to fight the blaze from the air.
At least 100 structures have been destroyed, but the intensity of the blaze has prevented officials from finding out exactly how many buildings and home have been destroyed.
The fire has claimed the life of one 62-year-old woman who perished in her cabin.
The Colorado blaze, dubbed the High Park fire, has grown to 46,600 acres from 43,300 acres in the past day.
Larimer County sheriff's office said the blaze was "10% plus" contained.
Firefighters have battled to build a containment line around the blaze that broke out Saturday about 100km northwest of Fort Collins, Colorado.
The Department of Homeland Security meanwhile said Tuesday it was working closely with emergency services tackling wildfires in a number of states.
In all, 19 active large fires are burning in nine states, "including one of the largest wildfires in New Mexico history and one of the largest wildfires in Colorado history," it said.
Some 4,500 extra firefighters have been dispatched by federal agencies, which are also providing emergency funding to help states cope with the costs of tackling the massive blazes.
