Poland says two of its citizens died in the blast
More victims are being identified from Monday night's suicide bomb attack on the Manchester Arena in Britain.
The mother of 15-year-old Olivia Campbell has confirmed her daughter was one of those killed.
Charlotte Campbell paid tribute to her daughter on Facebook, saying: "RIP my darling precious gorgeous girl Olivia Campbell taken far far to soon go sing with the angels and keep smiling mummy loves you so much."
Poland's foreign minister has also confirmed that two Polish nationals, Marcin and Angelika Klis, are among the dead.
They had been missing since the bombing at the Ariana Grande concert.
Mothers Alison Howe and Lisa Lees were both killed as they waited for their children to come out of the concert.
Mrs Howe's stepson Jordan said on Facebook: "They took a caring beautiful mum and step mother away from us all she was amazing to us all x love you loads Alison Howe xx".
Lisa Lees' brother Lee Hunter said: "For those who don't know Lisa is gone but never ever forgotten I love you Lisa I'll miss you so much".
Kelly Brewster, who was also killed in the attack, was at the concert with her sister.
Her partner said on Facebook: "Kelly really was the happiest she has ever been and we had so many things planned together. My daughter Phoebe will be absolutely devastated like we all are. Love you loads."
Others identified Tuesday include 18-year-old Georgina Callander and eight-year-old Saffie-Rose Roussos.
Roussos was a pupil at Tarleton Community Primary School, and had been attending the concert with her mother and her older sister.
Her headteacher, Chris Upton, said her death had come as a "tremendous shock" and he described Saffie as "simply a beautiful little girl in every aspect of the word".
Runshaw College, where Callander attended, said their thoughts and prayers go out to all of Georgina's friends, family, and all of those affected by this loss.
John Atkinson was also killed. The 26-year-old has been described as a "beautiful soul" by loved ones.
Many of the people injured are being treated for life-threatening conditions.
The bomb suspect has been named by police as 22-year-old Salman Abedi.
Islamic State has claimed one of its members carried out the terror attack at the sold-out concert.
Greater Manchester Police said a lone male attacker detonated an improvised explosive device in the suicide bombing.
Investigators are trying to establish whether the attacker was part of a wider network.
