Vancouver Police say 11 people are dead and at least 20 more have been injured after a car ramming attack in the Canadian city.
The incident came less than two days before the Canadian election, with both sides of politics pausing campaigning.
Here's what we know so far.
What happened?
Authorities say they were called to the incident shortly after 8pm Saturday evening local time, on the corner of Fraser St and East 41st Avenue, in Vancouver's southern suburbs.
At the time, the local Filipino community was celebrating "Lapu Lapu Day", in recognition of a Philippines national hero.
[EL: Vancouver map]One witness told Canadian broadcaster CTV he saw a black vehicle driving erratically in the area of the festival just before the crowd was struck.
Vancouver Police said they received reports a car had ploughed into a group of people.
Police said they had arrested a 30-year-old Vancouver man, who was "known" to them, at the scene of the incident on Saturday evening.
Police Interim Chief Steve Rai told a news press conference that the suspect "does have a significant history of interactions with police and health care professionals related to mental health".
Video of the aftermath of the attack that has been circulating on social media shows a young man in a black hoodie with his back against a chain-link fence, alongside a security guard and surrounded by bystanders screaming and swearing at him.
The man appears to be apologising in that video, although police have not commented on the vision.
What has the reaction been?
At a press conference on Sunday morning, Canadian Prime Minister Mark Carney said at least 20 people were injured.
"Last night, families lost a sister, a brother, a mother, a father, a son or a daughter. Those families are living every family's nightmare," Mr Carney told reporters in Hamilton, Ontario.
He also expressed his condolences to the country's Filipino community.
King Charles, who is Canada's head of state, said in a statement: "Both my wife and I were profoundly saddened to learn of the dreadful attack and utterly tragic loss of life in Vancouver, which took place as the Filipino community came together to mark the celebration of one of their most special festivals."
Vancouver Mayor Ken Sim said on social media he was "shocked and deeply saddened by the horrific incident".
"Our thoughts are with all those affected and with Vancouver’s Filipino community during this incredibly difficult time," he said.
What have police said?
Despite Mr Carney labelling the incident a "car ramming attack", police have been quick to downplay the prospect of terrorism.
"At this time, we are confident that this incident was not an act of terrorism," Vancouver Police said in an X post.
Police said the injured were taken to multiple nearby hospitals.
Will this impact the Canadian election?
Canadians go to the polls to choose their next government on Monday, local time.
On Sunday, Mr Carney put off some election campaigning but was expected to appear on the trail later in the day.
Conservative Party leader Pierre Poilievre said his thoughts were with Vancouver's Filipino community after the "horrific" news.
Mr Poilievre said many relatives and friends of victims would have a "deep hole in their hearts" after the incident.
