Ten people have been stabbed to death - with police investigating 13 crime scenes and hunting two suspects, in Canada.
Detectives don't have a motive yet, but warn suspects Damien and Myles Sanderson may have left the area.
It happened across an indigenous community, and nearby town, in the Saskatchewan province.
Jason Kerr is the editor of the Prince Albert Daily Herald in the country.
He says attacks like these are completely unusual in the area.
"We're used to seeing stories like this coming out of places like New York or Los Angeles.
"For us to see ten deaths due to stabbing in such small communities is unheard of."
Canadian Prime Minister Justin Trudeau has responded to the attacks calling them "horrific and heartbreaking."
Police say the suspects were seen traveling in a black Nissan Rogue and spotted in the city of Regina, about 320 km south of the attacks in the James Smith Cree Nation and the village of Weldon.
