VANCOUVER, British Columbia — A 30-year-old man was charged with multiple counts of murder on allegations he killed 11 people when he rammed a crowd of people at a Filipino heritage festival in Vancouver, as hundreds attended vigils across the city for the victims and the Canadian prime minister visited the site on the eve of a federal election.

Kai-Ji Adam Lo, 30, was charged with eight counts of second-degree murder in a video appearance before a judge Sunday, hours after he was arrested at the scene.
