Edmonton: Chain of traffic wrecks and pileups near Alberta were caused by a blizzard that swept across the Canadian plains.
The wrecks involved a bus, semi-trailer trucks and cars south of Edmonton, Alberta, sending about 100 injured travelers to hospitals, officials said.
One person was seriously hurt, said Sharman Hnatiuk of the Alberta Health Services office. She had earlier estimated that 300 people were hurt, four seriously. Many victims were taken to hospitals in nearby communities including Edmonton and Red Deer, she said.
The Royal Canadian Mounted Police closed part of Highway 2, the main road between Edmonton and Calgary, and were directing traffic away from the collision scene, said RCMP Staff Sgt. Grant MacDonald.
He said the crash involved several vehicles, including a large passenger bus and several semi-trailer trucks.
