The city of Yellowknife in Canada's Northwest Territories has been ordered to evacuate as wildfires threaten to reach the city by the weekend. The wildfires, which have already destroyed the community of Enterprise, are part of a devastating wildfire season in Canada. Yellowknife, with a population of 20,000, declared a state of emergency on Monday. The Northwest Territories has declared a state of emergency as it battles more than 200 wildfires. The road out of Hay River, another affected community, has been described as "treacherous" and supplies of food and petrol are running low. The Canadian military has been coordinating airlift operations to evacuate threatened communities in the region. The wildfires are being fueled by strong winds and a warmer and drier spring than usual. It is uncertain when evacuees will be able to return home, as the wildfires continue to burn across the country. Can Yellowknife be saved from the approaching wildfires?
