The Canadian province of Alberta raced to evacuate the entire population of Fort McMurray where an uncontrolled wildfire was taking hold in the heart of the country's oil sands region, with dry winds forecast for Wednesday that could fuel the blaze.

Alberta appealed for military help to battle the fire and airlift people from the smoke-filled city after authorities issued a mandatory evacuation order for 80,000, but officials said army and air force assistance would take two days to arrive.
