PHOENIX (Reuters) - Firefighters struggled against strong winds on Thursday to halt the advance of Arizona wildfires that have charred more than 30 square miles (78 square km) of dry ponderosa forest, brush and grass, and a blaze in nearby Colorado swelled overnight.
More than 1,000 firefighters in the two states battled at least five major blazes from the ground while air tankers and helicopters dropped water and fire retardant. Another fire erupted in Minnesota, encroaching on the northern town of Ely.
