Australian nurse Kirsty Boden was killed by terrorists as she ran towards danger in an effort to help people, her family have said.
She is the third person to named among the dead after three attackers ploughed into pedestrians on London Bridge and then stabbed people in Borough Market.
Her family paid tribute to her in a statement on Tuesday.
“Kirsty was loved and adored by her family, friends and boyfriend,” they said.
“She was the most outgoing, kind and generous person, who loved to help people. Helping people was what she loved to do in her job as a nurse and in her daily life.
“As she ran towards danger, in an effort to help people on the bridge, Kirsty sadly lost her life.
“We are so proud of Kirsty’s brave actions which demonstrate how selfless, caring and heroic she was, not only on that night, but throughout all of her life. Kirsty – we love you and we will miss you dearly.”
Her family have asked for privacy.
The family of an Australian woman who has been missing since the attack said they are “bracing for the worst”, Australian media have reported.
A friend on Facebook said Sara Zelenak, 21, became separated on Saturday night as they ran for their lives.
Australia’s ABC News reported a woman, who identified herself as Ms Zelenak’s aunt Tara, spoke outside the family’s home in Ormiston, near Brisbane, in Queensland on Tuesday.
“We are obviously very upset and emotionally distraught at this time. The family is trying to keep it together but bracing for the worst,” she told the news service.
Tara reportedly broke down as she described her “absolutely beautiful” niece as “the girl next door” and a “very special, kindred spirit”.
“She’s one of those girls that doesn’t drink, doesn’t do drugs, doesn’t do anything wrong,” Tara added.
Ms Zelenak’s mother, Julie Wallace, told Australian radio station 97.3FM her daughter had been travelling in Europe since March and was working as an au pair for a family in London, caring for two young boys.
She said she first heard news of the terror attack by text message as she was returning home from Canberra.
“I thought ‘oh no, not again’, and didn’t think much of it,” she said.
But she told listeners she received a “strange call” from the family her daughter was staying with, who told her they had given her the night off to go out with a friend.
“She never came back,” said Ms Wallace, who described her daughter as a “very smart, sensible girl”, adding: “She doesn’t do anything wrong.
She said Ms Zelenak had been at Westminster the day before 52-year-old terrorist Khalid Masood killed five in a car and knife rampage, and had planned to go to the Ariana Grande concert in Manchester, where suicide bomber Salman Abedi murdered 22 victims.
“Everything, she’s just missed,” said Ms Wallace, who added she was planning to come to London with her husband to look for her daughter.
