A ferocious wildfire wreaking havoc in Canada doubled in size and officials warned that the situation in the parched Alberta oil sands region was "unpredictable and dangerous."
"This remains a big, out of control, dangerous fire," Public Safety Minister Ralph Goodale said of the raging inferno bigger than London that forced the evacuation of the city of Fort McMurray.
The wildfire had doubled in size in one day and continues to grow, the Alberta Emergency Management Agency said in an update late Saturday, according to AFP.
"Fire conditions remain extreme," it said.
