A school shooting in the Canadian province of Saskatchewan left four people dead and two others critically injured on Friday, Canadian Prime Minister Justin Trudeau confirmed.

The shooting occurred at La Loche Community School, a school for grades 7 through 12. The school was placed on lockdown and one suspect was taken into custody, CBC News reported. The school is located in the aboriginal village of La Loche, which is located in northern Saskatchewan. It is a small community of about 3,000 residents.

"I want to thank the first responders who acted quickly and bravely," Trudeau said at a press conference. He added that the situation was "no longer active."

"I ran outside the school," Noel Desjarlais, a 10th grade student at the school, told CBC News. "There was lots of screaming. There was about six, seven shots before I got outside. I believe there was more shots by the time I did get out."

Brad Wall, the premier of the Canadian province of Saskatchewan, issued a statement in response to the shooting. He said that "[w]ords cannot express my shock and sorrow at the horrific events today in La Loche. My thoughts and prayers are with all the victims, their families and friends and all the people of the community."
