Canadian oil city lifts wildfire evacuation orders

"We are so pleased to be able to welcome people home and have them return home safely," Fort McMurray Mayor Sandy Bowman said, thanking the more than 6,000 residents who had been ordered to leave for their "patience, resolve and strength."

Much-needed rains have reduced the intensity of the wildfire in western Canada's Alberta province and "significant progress" has been made to contain its northern edge, a city statement said.

However, more than 19,000 hectares (47,000 acres) continued to burn out of control, Alberta firefighters said in a Saturday morning update, which noted more forecasted rain.

The evacuation order for the Fort McMurray residents came Tuesday as the rapidly spreading fire approached the city.

In 2016, it was hit by a fire that prompted the evacuation of 90,000 people, in a major catastrophe that saw 2,500 buildings destroyed and billions of dollars in damage.

Canadian authorities have been bracing for the possibility of another devastating wildfire season, after the country's worst-ever last year saw blazes from coast to coast, charring more than 15 million hectares of land.

A federal government tracker showed 114 active fires as of Saturday afternoon, including 42 in Alberta and 40 in westernmost British Columbia.
