At least 11 people were killed and more than 20 injured when a car drove into a street festival in Vancouver, Canada.
The incident occurred on Saturday night local time, according to Vancouver Police, as residents celebrated "Lapu Lapu Day" — a celebration of the city's Filipino community.

At a midnight press conference, police said the suspect was "known" to them but did not elaborate.
In a later post on social media, police said they were "confident" the incident was not an act of terrorism.
Canadian Prime Minister Mark Carney later said 20 people were injured in what was being described by authorities as a "car ramming attack", but that police did not believe it was a terrorist attack.
Thousands of people were attending the festival when an SUV drove into the crowd at speed, according to local media.
Witnesses told the Vancouver Sun the final performer had just finished when the incident occurred on a street lined with food trucks and market stalls.

"Our thoughts are with all those affected and with Vancouver’s Filipino community during this incredibly difficult time," he said.
Philippines President Ferdinand Marcos Jr said the Philippines consulate was working with Canadian authorities to ensure that the incident would be thoroughly investigated.
Vancouver city councillor Peter Fry told CTV News he had also been at the event earlier in the day.
"This was a great day. A wonderful event. Huge community event," he said.
"To have it end in tragedy like this, it won't break us or the community but it's horrible."

"We are monitoring the situation closely, and thankful to our first responders for their swift action," he said.
He also paused election campaigning on Sunday — the final day for himself and Conservative leader Pierre Poilievre to make their pitches to voters ahead of an election on Monday.
Mr Poilievre said his thoughts were with Vancouver's Filipino community after the "horrific" news.
