At least nine people were killed and multiple others were injured in Vancouver after a vehicle drove into a crowd at a Filipino street festival in the western Canadian city, police said on Saturday.

Police said they were investigating a mass casualty incident and had arrested a 30-year-old Vancouver man at the scene, but did not immediately give the number of fatalities or injured, saying they would have more information in the morning.

“At this time, we are confident that this incident was not an act of terrorism,” Vancouver police said in an X post.

At a midnight press conference, police said that the suspect was “known” to them but did not elaborate. The man was initially taken into custody by people at the scene.

“There was a number of deceased, a number also injured. It would be unfair for me to speculate on exact numbers as the victims were taken to multiple hospitals in the region,” said Vancouver interim police chief Steve Rai.

The incident happened shortly after 8pm near East 41st Avenue and Fraser Street, where the Lapu-Lapu Day Block Party, celebrating a Philippine national hero, was taking place.
