The Cree community of Mistissini in northern Quebec was placed under immediate lockdown early Thursday following a shooting that left several people dead, according to community leadership. Chief Michael Petawabano of the Cree Nation of Mistissini announced the confinement shortly before 7 a.m., urging residents to remain indoors and cooperate with police as an active investigation continues. Under the confinement order, residents have been instructed to stay inside their homes until further notice. All schools, offices and community buildings have been closed, and travel into and out of the community is strictly restricted. Mistissini, home to about 4,000 people, is located just under 800 kilometers north of Montreal.
