The drought sweeping much of the United States is contributing to an upsurge in wildfires.

In June, more than 6,500 wildfires burned an estimated 500,000 hectares across the country, making for the second-worst June for fire damage in the past 13 years.

In the state of Oklahoma, flames have destroyed dozens of homes and forced residential areas to be evacuated.
