A fire at a potash mine near Saskatoon started in the engine of an underground water truck. It took eight hours for emergency workers to put out the flames and clear smoke while the miners waited in refuge stations and sealed-off passageways. About half made it safely to the surface overnight. But a power outage prevented the others from leaving and also cut phone service to the shelters. More than a day later the last of the 96 miners were finally brought to the surface.
