Three people are dead and four others are badly injured after a head-on collision on a southern Alberta highway.
RCMP say the crash happened late Monday afternoon near the town of Olds.
Corporal Shawn Morgan says one of those killed was the lone occupant of an SUV.
The rest were in a minivan, with the driver and one passenger found dead at the scene.
Three passengers are in critical condition, two of which were airlifted to Calgary by air ambulance.
The others were taken by ground ambulance to area hospitals.
Morgan says weather and alcohol are not considered factors but road surface conditions may have played a part, though the crash is still under investigation.
