Here is what we know so far about the victims of the terror attack, the deadliest in Britain since the 2005 London bombings.
‘Sing with the angels’
Olivia Campbell, 15, has been named as a victim of the bombing at an Ariana Grande concert in the Manchester attack.
Her mother, Charlotte Campbell, paid tribute to her on Facebook saying: “go sing with the angels”.

‘Beautiful little girl’
Eight-year-old Saffie Rose Roussos from Leyland, a town in Lancashire, northwest England, is so far the youngest named fatality.
She attended the concert with her mother and older sister. Friends said they were both being treated for their injuries in hospital.
Chris Upton, headteacher at the Tarleton Community Primary School, described Saffie as “a beautiful little girl in every sense of the word”.
“She was loved by everyone and her warmth and kindness will be remembered fondly. Saffie was quiet and unassuming with a creative flair,” he said.
“The thought that anyone could go out to a concert and not come home is heartbreaking.”

The death of Georgina Callander, believed to be 18, was confirmed by her school, the Runshaw College Sixth Form Centre in Lancashire.
“It is with enormous sadness that it appears that one of the people who lost their lives in Monday’s Manchester attack was one of our students here,” the school said, adding that she had been studying health and social care.
Her former school, Bishop Rawstorne Church of England Academy, added: “Georgina was a lovely young student who was very popular with her peers and the staff and always made the most of the opportunities she had at the school.
“All of our students will gather together today for a time of prayer and reflection and to give thanks for the life of Georgina.”

John Atkinson, 26, from Bury in Lancashire, was named by friends as one of those killed.
His Facebook account has been “memorialised” — a process only made possible by verified family members contacting the website directly.
John was “one in a million and loved by so many,” wrote Hayley Turk, who organised an online fund for his family.
“A true gentleman,” she added.

In a Facebook post soon after the attack, York College student Alex Klis made a plea to help find her parents, Angelika and Marcin Klis.
“If anyone comes across my parents please, please let me know as they’ve been missing ever since the attack, this is a picture taken tonight so this is exactly what they were wearing,” she wrote.
Polish parents died in the suicide attack in the English city of Manchester, Poland’s Foreign Minister Witold Waszczykowski confirmed on Wednesday.
“The parents came after the concert to collect their daughters and unfortunately we have information that they are dead,” Waszczykowski told private radio RMF FM.
“The children are safe.”
Alison Howe and her friend Lisa Lees, who arrived at the arena to pick up their children, have been named victims.
Ms Howe’s stepson Jordan Howe posted a photo of her on Facebook, saying: “They took a caring beautiful mum and stepmother away from us all she was amazing to us all x love you loads Alison Howe xx.”
Lee Hunter, the brother of Lisa Lees, posted to Facebook: ‘For those who don’t know, Lisa is gone but never ever forgotten.
“I love you Lisa, I’ll miss you so much.”
An earlier Facebook post by Lisa Lees’ daughter, Lauren Ashleigh Lees, shared a photo of her before her death had been confirmed:
“Recent picture of my mum, she’s no longer blonde like the photo originally shared.
“We are all really worried, still haven’t heard a thing, thank you all for your amazing support.”
‘You died a hero’
Kelly Brewster, 32, is another victim of the terror incident.
She helped protect her niece, Hollie Booth, who broke two legs during the attack, and her sister Claire Booth, according to Hollie’s grandmother Tracy Booth.
“Would just like to say Kelly Brewster, you died a hero,” Tracy Booth wrote on Facebook.
“You saved your sister Claire Booth and my granddaughter Hollie Booth, so Kelly, you fly high with the angels.”
“We got the news last night that our wonderful, iconic and beautiful Martyn didn’t survive,” Mr Hayward wrote.
“Thankfully I have his wonderful family and amazing friends to keep each other strong.”
Among the scores of wounded who were treated at Manchester Arena after the attack, 59 people were taken to hospital, including 12 children under the age of 16.
There were also walking wounded who presented themselves at Manchester hospitals.
“There are a number of individuals who have very, very serious injuries and are requiring intensive care and people who are going to be in hospital for a long time,” said David Ratcliffe, medical director of the North West Ambulance Service.
In a statement outside Downing Street on Tuesday, Prime Minister Theresa May said that many of the wounded were being treated for “life-threatening conditions”.
The Manchester Evening News, the city’s main newspaper, launched a crowdfunding campaign to support the families of those affected by the attack.
The fund had raised more than £500,000 ($650,000, 580,000 euros) by 1800 GMT Tuesday.
Crowdfunding was also under way for individual victims, and for a homeless man begging at the venue who cradled a woman who died in his arms.
