The driver of a car struck revelers at a street festival in Canada, killing and injuring an unknown number of people at the event celebrating Filipino culture, police said.

The vehicle entered the street at 8:14 p.m. Saturday where people were attending the Lapu Lapu Day festival, the Vancouver Police Department said in a social media post.

“A number of people have been killed and multiple others are injured after a driver drove into a crowd,” police said. The exact number of dead or injured was not immediately available.

A 30-year-old Vancouver man was arrested at the scene and the department’s Major Crime Section is overseeing the investigation, police said.

“At this time, we are confident that this incident was not an act of terrorism,” the police department posted early Sunday.

The festival was being held in a South Vancouver neighborhood. Video posted on social media showed victims and debris strewn across a long stretch of road, with at least seven people lying immobile on the ground. A black SUV with a crumpled front section could be seen in still photos from the scene.

James Cruzat, a Vancouver business owner, was at the event and heard a car rev its engine and then “a loud noise, like a loud bang” that he initially thought might be a gunshot.

“We saw people on the road crying, others were like running, shouting, or even screaming, asking for help. So we tried to go there just to check what was really actually happening until we found some bodies on the ground. Others were lifeless, others like, you know, injured,” Cruzat said.

“It was terrible to see that kind of incident, that situation. It was heartbreaking,” Cruzat said. “I couldn’t even imagine that it’s actually happening in real life, because normally we see that on TVs or movies. But when you are in that kind situation, it was really shocking. Like, you couldn’t think really, really well. You couldn’t do anything but to pray for them.”

Vancouver Mayor Kenneth Sim said in a social media post that the city would provide more information when possible.

“I am shocked and deeply saddened by the horrific incident at today’s Lapu Lapu Day event,” Sim said. “Our thoughts are with all those affected and with Vancouver’s Filipino community during this incredibly difficult time."

Prime Minister Mark Carney and other Canadian political figures posted messages expressing shock at the violence, condolences for victims and support for the community celebrating its heritage at the festival.

“I offer my deepest condolences to the loved ones of those killed and injured, to the Filipino Canadian community, and to everyone in Vancouver. We are all mourning with you,” Carney wrote.

“As we wait to learn more, our thoughts are with the victims and their families — and Vancouver’s Filipino community, who were coming together today to celebrate resilience," wrote Jagmeet Singh, leader of the New Democratic Party, who was at the festival earlier in the day.

“My thoughts are with the Filipino community and all the victims targeted by this senseless attack. Thank you to the first responders who are at the scene as we wait to hear more,” Conservative Party leader Pierre Poilievre wrote.

David Eby, the premier of British Columbia, the province where Vancouver is located, said he was shocked and heartbroken. “We are in contact with the City of Vancouver and will provide any support needed,” Eby wrote.
