What happened?
Just after 18:00 BST on Monday, a car collided with a number of pedestrians towards the end of the parade route on Water Street.
In footage verified by the BBC, fans could be seen confronting the car before it ploughed through the crowds.
Police said on Tuesday that, overall, there had been 65 confirmed casualties.
It said 50 people were treated at hospitals and of these, 11 remained in hospital but were in a stable condition and recovering well.
Four children were among the injured, one of whom was seriously hurt, police had said on Monday. Four people, including a child, were also lifted from beneath the car.
What did witnesses see?
Video from the scene shows the car ploughing into the a group of people.
Other footage shows people striking the car after it stopped, with the back windscreen shattered.
One eyewitness, BBC reporter Matt Cole, described seeing a car coming through the crowd that "just wasn't stopping".
He said it was being chased by a group of men "who were trying to bang on the side of it and throw things at it".
He estimated the car was travelling at "more than 20 [mph]".
He said his initial assumption was that the driver just wanted to "barge through crowds because they didn't want to wait".
Another witness, Matthew O'Carroll, 28, from Runcorn, saw the car approaching the top of Water Street.
He said the vehicle had been going at a "decent" speed and that the driver had been beeping as he went through the crowd.
The BBC has also heard from other witnesses, including Daniel Eveson from Telford, Shropshire, and Jack Trotter, from Newtownards, County Down, who were injured in Monday's collision.
For a moment, he did not know if his partner or son had survived, he said.
He was able to locate his son, who was unharmed, while his partner remained in hospital and was waiting to hear whether she could return home.
Mr Trotter - who had travelled to the parade with his girlfriend Abbie Gallagher - was hit by the car as it drove into fans on Water Street and sustained injuries to his back and leg.
He has since been discharged from hospital and said he feels "very lucky to be alive".
Ms Gallagher told the BBC that she saw the car coming towards them and remembered putting her hands on the bonnet to protect herself.
"I was towards the driver's side and Jack was on the passenger side when the car was coming at us," she said. "It was a good five minutes later until I found Jack, and I just saw him and we hugged each other."
Where did it happen?
Water Street is near the Strand, where moments before the incident occurred Liverpool FC had paraded the Premier League trophy from the top of a bus.
Thousands of people had come out to celebrate the team's victory. The incident happened about a mile before the parade's finishing point.
Was the road closed?
Water Street was closed to traffic, the police said on Tuesday.
However, they said the roadblock was temporarily lifted on Monday to allow an ambulance to attend to a member of the public who was having a suspected heart attack.
"It is believed the driver of the Ford Galaxy car involved in this incident was able to follow an ambulance onto Water Street", she said.
What has been said?
Prime Minister Sir Keir Starmer is being kept updated on the latest developments.
He posted on X: "The scenes in Liverpool are appalling - my thoughts are with all those injured or affected.
"I want to thank the police and emergency services for their swift and ongoing response to this shocking incident."
Conservative leader Kemi Badenoch said the pictures were "deeply worrying".
"My thoughts are with all those affected, and the emergency services as they respond to what appears a horrific incident," she said.
King Charles III, who has been in Ottawa to open the 45th session of Canada's parliament, said he and Queen Camilla were "deeply shocked and saddened" by Monday's events.
"At this heartbreaking time for the people of Liverpool, I know that the strength of community spirit for which your city is renowned will be a comfort and support to those in need", the post on X said.
Liverpool FC said it was in contact with the police and that its "thoughts and prayers are with those who have been affected by this serious incident", with rivals Everton FC echoing the sentiment.
Liverpool's staff celebrations are understood to have been postponed because of the incident.
The Premier League also released a statement on Monday, saying "everyone at the Premier League is shocked by the appalling events in Liverpool this evening, and our heartfelt thoughts go out to all those injured and affected."
Liverpool City Region Mayor Steve Rotherham told the BBC a day of "absolute celebration" had been "overshadowed" by the incident. He urged the public to avoid speculation while police continue their investigation.
Police said the crash was "not currently being treated as terrorism" - they said they believed it to be an isolated incident "and we are not currently looking for anyone else in relation to it".
Police only define events as terrorism if they are considered to have been intended to influence the government or intimidate the public for the purpose of "advancing a political, religious, racial or ideological cause".
