A vigil has been held to pay tribute to the victims killed in the London Bridge terror attack and to honour the emergency services and members of the public who responded to the incident.
Former University of Cambridge students Saskia Jones, 23, and Jack Merritt, 25, were fatally stabbed by 28-year-old convicted terrorist Usman Khan in Friday's attack.
Mayor Sadiq Khan was among those who gathered at 11am at a remembrance service at Guildhall Yard, where Londoners will be able to lay flowers.
Also present were Prime Minister Boris Johnson, Labour leader Jeremy Corbyn, Metropolitan Police Commissioner Cressida Dick and Home Secretary Priti Patel.
Mr Khan said: "We come together this morning as Londoners to remember, to honour and to mourn the innocent lives lost as a result of this horrific terrorist attack on Friday."
He added: "The best way to defeat this hatred is not by turning on one another but by focusing on the values that bind us."
The mayor thanked the public and the emergency services who "ran towards danger, risking their lives to help others".
It comes as West Midlands Police said a 34-year-old man arrested in Stoke-on-Trent on suspicion of preparation of terrorist acts has been recalled to prison due to a suspected breach of his licence conditions.
Officers from the West Midlands Counter Terrorism Unit arrested the man after a search of his home address on Saturday and inquiries into the suspected offences are continuing.
The force has said that there is no information to suggest that the arrested man was involved in the incident at London Bridge.
Khan, 28, was on licence and wearing an electronic monitoring tag when he launched the violent attack, which injured three others, after he was invited to the prisoner rehabilitation conference on Friday afternoon.
The attack has prompted the British Ministry of Justice to review the licence conditions of every convicted terrorist released from prison, which Mr Johnson told the BBC was "probably about 74" people.
Mr Johnson has vowed to take steps to ensure people are not released early when they commit serious offences.
But the family of Mr Merritt, from Cottenham, Cambridgeshire, asked for his death not to be used to justify introducing "even more draconian sentences" on offenders in a heartfelt tribute released yesterday.
They said: "He lit up our lives and the lives of his many friends and colleagues, and we will miss him terribly.
"Jack lived his principles; he believed in redemption and rehabilitation, not revenge, and he always took the side of the underdog.
"We know Jack would not want this terrible, isolated incident to be used as a pretext by the government for introducing even more draconian sentences on prisoners, or for detaining people in prison for longer than necessary."
Ms Jones, a volunteer with the prisoner rehabilitation scheme from Stratford-upon-Avon, Warwickshire, was described by her family as having a "great passion" for providing support to victims of crime.
In a statement, they said: "She was intent on living life to the full and had a wonderful thirst for knowledge, enabling her to be the best she could be.
"Saskia had a great passion for providing invaluable support to victims of criminal injustice, which led her to the point of recently applying for the police graduate recruitment programme, wishing to specialise in victim support."

Khan, who was living in Stafford, was given permission to travel into the heart of London by police and the probation service.
Convicted of terror offences in February 2012, he was released from prison on licence in December 2018, halfway through his 16-year prison sentence.
He launched the fatal attack at an event held by Learning Together, a programme associated with the university's Institute of Criminology, at Fishmongers' Hall near London Bridge.
Armed with two knives and wearing a fake suicide vest, he was tackled by members of the public, including ex-offenders from the conference, before he was shot dead by police.
One of the three people injured in the attack has been allowed to return home, while the other two remain in a stable condition in hospital, Met Police said.
No one else is being sought over the attack.
