Prime Minister Imran Khan on Tuesday condemned killing of four members of a Canadian family of Pakistani origin, describing it as an "act of terrorism" underscoring growing "Islamophobia" in Western countries.
On Sunday, a 20-year-old man, wearing vest-like body armour, slammed a pickup truck into a Pakistani family of five, killing four of them.
Police have said that it was "a planned, premeditated act motivated by hate".
"There is evidence that this was a planned, premeditated act, motivated by hate. It is believed that these victims were targeted because they were Muslim," said Detective Superintendent Paul Waight of the London, Ontario Police. "There is no known previous connection between the suspect and the victims."
The driver, Nathaniel Veltman, was arrested five minutes later, seven kilometres away from the scene.
Meanwhile, Pakistan's Foreign Minister Shah Mahmood Qureshi also took to Twitter to express grief over the incident, saying three generations of Pakistani-Canadians had been killed for their faith.
Canadian Prime Minister Justin Trudeau said he was “horrified” by the incident and described it as a terrorist attack.
"This was a terrorist attack, motivated by hatred, in the heart of one of our communities," he said on Tuesday.
According to media reports, a 74-year-old woman was pronounced dead at the scene Sunday night and the other four family members, a 46-year-old man, a 44-year-old woman, a 15-year-old girl, and a nine-year-old boy, were taken to hospital, where the two adults and the teen died.
The boy is still recovering, and is in a serious but non-life-threatening condition. Veltman has been charged with four counts of first-degree murder and one count of attempted murder.
