Canada wildfire: Footage shows entire street razed to ground

Officials in Canada say that a wildfire that is raging in and around the oil town of Fort McMurray will double in size in the next 24 hours.

Walls of flames 200-feet high have forced officials to suspend a convoy along the only road to safety.

More than 80,000 homes have been evacuated.
