Four members of a Muslim family were killed in a “premeditated” vehicle attack on Sunday, Canadian police say.
A pickup truck mounted the curb and hit the victims in the city of London, Ontario province. A boy aged nine, the family’s only survivor, is seriously injured in hospital.
A 20-year-old Canadian man has been charged with four counts of murder and one count of attempted murder.
Police believe the collision was a planned hate crime.
“It is believed that these victims were targeted because they were Muslim,” Detective Superintendent Paul Waight told a news conference.
Police are weighing possible terrorism charges, he said.
It is not yet known if the attacker – named as Nathanial Veltman, 20, of London – has ties to any specific hate groups, said Det Supt Waight.
He was arrested without incident at a shopping centre about 6km (4.8 miles) from the crime scene.
“There is no known previous connection between the suspect and the victims,” Det Supt Waight said, adding that the suspect was wearing a vest that appeared to be “like body armour”.
Ontario Premier Doug Ford was among those who paid tribute to the victims, tweeting: “Hate and Islamophobia have NO place in Ontario.”
“This was an act of mass murder, perpetrated against Muslims, against Londoners, and rooted in unspeakable hatred,” said London Mayor Ed Holder.
In a statement, Mayor Holder said he was speaking “on behalf of all Londoners when I say our hearts are broken”.
“We grieve for the family, three generations of whom are now deceased.”
The mayor’s statement added that he had ordered flags outside London City Hall to be lowered for three days of mourning.
The National Council of Canadian Muslims (NCCM) said in a statement that the attacker should face terrorism charges.
“A man allegedly got in his car, saw a Muslim family walking down the street, and made the decision that they do not deserve to live,” said the organisation’s CEO Mustafa Farooq.
“He did not know them. This is a terrorist attack on Canadian soil, and should be treated as such,” his statement continued.
