NIPAWIN, Saskatchewan (AP) — A crash between a transport truck and a bus carrying a junior hockey team in the province of Saskatchewan has left people dead and others seriously injured, Canadian police said late Friday.

Royal Canadian Mounted Police Insp. Ted Munro could not say how many people have died or are hurt.

The bus was carrying the Humboldt Broncos of the Saskatchewan Junior Hockey League to the town of Nipawin for a playoff game. It collided with a transport truck.

"It's a horrible accident, my God," said Darren Opp, president of the Nipawin Hawks hockey team. "It's very, very bad."

Opp said a semi T-boned the players' bus, adding that the coaching staff and players from the Hawks are waiting to help.

"They are sitting in the church just waiting to hear any good news," he said. "There's uncles and moms and dads waiting to hear whether their sons and nephews are OK."

Pastor Jordan Gadsby at the Apostolic Church in Nipawin said more than a hundred people gathered at the church. "Some of them are waiting to hear if their kids are alive."

Gadsby said they know there are multiple fatalities, but they haven't heard how many.

Kevin Henry, a coach who runs a hockey school in Prince Albert, said people are in shock. "It is sort of every parent's worst nightmare."

"This is I would think one of the darkest days in the history of Saskatchewan, especially because hockey is so ingrained in how we grow up here," Henry said.

The Saskatchewan Junior Hockey League is a Junior 'A' hockey league under Hockey Canada, which is part of the Canadian Junior Hockey League. It's open to North American-born players between the ages of 16 and 20.

RCMP said the collision occurred late Friday afternoon.

"I cannot imagine what these parents are going through, and my heart goes out to everyone affected by this terrible tragedy, in the Humboldt community and beyond," Canadian Prime Minister Justin Trudeau tweeted.
