A pile-up involving around 200 vehicles in Canada is being blamed on sudden blizzard-like conditions.
Firefighters said two people were still trapped after the mass crash on Wednesday in La Prairie, Quebec.
Police added about a dozen people were taken to hospital with injuries after the incident on Highway 15, with the crashed vehicles stretching for a kilometre.
Transport Minister Francois Bonnardel told reporters in Quebec City the pile-up took place in an area where heavy winds come off the St Lawrence river, creating sudden blizzard-like conditions.
Mr Bonnardel said: “People were driving, there were strong winds… and, suddenly, you couldn’t see anything.
“And then, well, the pile-up started.”
Police spokesman Sgt Stephane Tremblay said about 50 vehicles were able to drive away from the collision, but 75 others would need to be towed away.
