More tragic news to come out of the London Bridge terror attack, as the family of missing Brisbane nanny Sara Zelenak confirms she’s been found dead.

Her mum, Julie Wallace – who flew to London to help track down her daughter – shared the devastating news on Facebook a short time ago.

“Sara Zelenak is confirmed dead they found her body and has DNA tests confirmed thank you for all the overwhelming love and support from everyone,” she wrote.

The 21-year-old was leaving a bar called London Grind, near the bridge, when the van carrying three terrorists – whose rampage on the bridge and through Borough Market killed 7 and injured dozens more – crashed.

She became separated from the friend she was with at the time and an appeal to locate her was immediately launched by friends and family on social media.

“We believe she dropped her phone in the chaos and now it is flat,” read a Facebook call out.

In the days since, fears have grown that Sara was either run over and not yet identified or fell off the bridge and drowned.

She is now the second Australian to be killed in the brutal attack, after the family of South Australian nurse Kirsty Boden confirmed her death.

The 28-year-old’s family said she died running towards the carnage, trying to help victims who had been mowed down by the van or stabbed.

RIP Sara and Kirsty. 3
