Three people died and 24 others were injured after an all-terrain sight-seeing bus rolled over at a Canadian park in Alberta on Saturday afternoon, federal police said.
There were 27 passengers total on board, a Royal Canadian Mounted Police spokesperson said, en route to view glaciers at Columbia Icefield in Jasper National Park.
Cpl. Leigh Drinkwater told media the Jasper detachment of the RCMP were responding along with local police departments, paramedics, an air ambulance service and Parks Canada.
A spokesperson for the tour company told the Canadian Broadcasting Corp. acknowledged one of its Ice Explorer off-road buses overturned en route to the glacier but declined to offer further details.
A witness told CityNews that a rockslide pushed the vehicle over while stranding two other buses — with their passengers being airlifted out.
