A wildfire that forced thousands of residents from their homes in western Canada's oil sands hub of Fort McMurray earlier this month is now under control, Alberta officials said Wednesday.

Alberta wildlife officials said the blaze remains less than six kilometers (3.7 miles) from the community and is about 190 square kilometers (118 square miles) in size.

About 6,600 residents in four neighborhoods were ordered out for several days as fierce winds whipped flames close to the community.

The rest of those in the city of 68,000 were told they may have to leave on short notice. Those who were told to leave were able to return days later.

The cause of the fire remained under investigation.

For some, the blaze brought back difficult memories of 2016, when wildfires forced a mass evacuation of the city and burned more than 2,000 homes.
