WATCH: ITV Anglia's Elodie Harper reports on the commemorative events
The family and friends of two former Cambridge University students sobbed as a vigil was held in their memory in the city centre.
Jack Merritt and Saskia Jones were killed in a terror attack on London Bridge on Friday, 29 November.
On Monday, hundreds gathered in Cambridge's Market Square to remember the pair.
Jack's girlfriend broke down in tears as she clutched a cuddly toy, surrounded by the Merritt family.
Jack, 25, and Saskia, 23, were both working at a prisoner rehabilitation event organised by the University at Fishmongers' Hall near London Bridge on Friday.
That was where Usman Khan, 28, who was taking part in the conference, began an attack which saw him stab five people and ended with him being killed by armed police.
James Morgans, a university friend of Saskia, paid tribute to her:
“Jack Merritt, our beautiful, talented boy, died doing what he loved, surrounded by people he loved and who loved him. He lit up our lives and the lives of his many friends and colleagues, and we will miss him terribly.
At the same time as the vigil in Cambridge, a similar event took place in London featuring Boris Johnson, Jeremy Corbyn and Mayor of London Sadiq Khan.
He called for people to come together following the killings and work for a future "not defined by hatred but defined by hope, unity and love".
“Saskia was a funny, kind, positive influence at the centre of many people’s lives. She had a wonderful sense of mischievous fun and was generous to the point of always wanting to see the best in all people.
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.
No-one else is being sought over the attack.
