Canadian Prime Minister Justin Trudeau joined several thousand mourners in a vigil Tuesday evening to remember three generations of a Canadian Muslim family killed in what police said was a premeditated hate crime, as a grieving community stood united in the midst of the crisis.

"This is our city," Bilal Rahhal, chair of the London Muslim Mosque, told the crowd. "Never allow anyone to make you think otherwise because of the color of your skin, your faith, or where you were born. ... This is our city and we're not going anywhere."

On Sunday, four members of the family were killed as they were out on an evening walk near their home in London, Ontario, when police say a man rammed them with his pick-up truck, targeting them because of their religion.
