Fort McMurray,Alberta fire: Entire city forced to flee as inferno rages

The sky in northern Alberta's Fort McMurray resembled a wall of fire and smoke as a mammoth inferno swallowed parts of the Canadian city. Authorities ordered the evacuation of about 88,000 people, including the entire city of Fort McMurray.A state of emergency across the province was declared later in the day.The blaze has already destroyed 80% of Fort McMurray's Beacon Hill community.In all, some 1,600 structures have been destroyed by the fire, Alberta Premier Rachel Notley said. However, there have been no reports of deaths or injuries, officials said. High winds, warm weather and dry conditions were expected to create "explosive conditions" for fire growth and make it difficult for firefighters to keep up.
