At least 11 people have been killed after a car was driven into a crowd at a festival in Vancouver, police have confirmed.

Canadian Prime Minister Mark Carney said more than 20 people were injured in the incident, which occurred at approximately 20:14 local time on Saturday (03:14 GMT on Sunday).

A 30-year-old male suspect is in custody and the Vancouver Police Department said it was “confident that this incident was not an act of terrorism”. An investigation into the incident is ongoing.

Police said the suspect had driven into pedestrians at the annual Lapu Lapu festival, which celebrates Filipino culture, at East 43rd Avenue and Fraser in the south of the city.

Steve Rai, Vancouver Police’s interim chief, told a news conference that there had been one vehicle and one suspect involved in the incident. Mark Carney said police were calling it a “car-ramming attack”.

The owner of a food truck selling bao buns at the festival, Yoseb Vardeh, told the BBC World Service that the attack happened right in front of his van.

“This guy, he killed some of my customers,” he said. “There was people waiting for their buns that got hit.”

Mr Vardeh added: “I stepped outside of my food truck and I just saw bodies underneath people’s food trucks, husbands crying out for their wives or their kids… it was just horrible.”

Unverified footage posted on social media showed a number of police cars, ambulances and fire engines at the scene, with injured people lying on the ground.

Police initially said nine people were killed in the incident, but that was revised up to 11 during an update on Sunday morning.
