A man suspected of killing 10 people in a mass stabbing in Canada has been found dead – with injuries that were not self-inflicted.

Canadian police have named him as Damien Sanderson. They have warned that another suspect – his brother Myles – is a threat to the public.

At a news conference, officers said Myles may have been injured and could seek medical attention.

“Even if he is injured, it does not mean he is not still dangerous. Myles has a lengthy criminal record involving both persons and property crimes,” they added.

“We consider him armed and dangerous. Do not approach him. If you know of his whereabouts, call 911.”

The series of knife attacks happened at various locations in Saskatchewan, including James Smith Cree Nation, about 125 miles north-east of Saskatoon.

The injury toll has risen to 18, with police saying that some appeared to have been targeted, while others appeared to have been attacked at random.

It is one of the deadliest mass killings in Canada‘s history.

In a televised statement, Canadian Prime Minister Justin Trudeau described the stabbings as “shocking and heart-breaking”.

He added: “This kind of violence, or any kind of violence, has no place in our country.

“The priority is keeping you and your loved ones safe so please be careful.”
