WATCH: Susanna Reid breaks down after talking to mother of missing girl from Manchester terrorist attack

Susanna Reid broke down in tears earlier today as she covered last night’s terrorist attack in Manchester on Good Morning Britain, with a suicide bomber setting off an explosive device at the end of Ariana Grande’s concert.

It all got too much for Susanna when the heartbroken mother of missing gig-goer Olivia Campbell issued a devastating plea to find her 15-year-old daughter, who attended Ariana’s show last night and has not yet been located.

Susanna couldn’t fight back the tears.

Speaking to the hosts, Olivia’s mother Charlotte, 36, begged for information about her daughter, who went to the concert with her best friend, Adam Lawler.

Adam is currently being treated at the Manchester Royal Infirmary but Olivia’s mobile phone is turned off and desperate calls around local hospitals have proven unsuccessful.

Speaking to the Manchester Evening News, Charlotte previously explained: “I know where Adam is and I know that Olivia isn’t with him.

“I’ve been told by the police that she’s registered as a missing person.

“She had her phone with her but it’s dead, I don’t know whether she’s lost it in the stampede to get out of there, but she knows by number off by heart so I know she can contact me if she’s able to.”

Shortly after speaking to Charlotte, mum-of-three Susanna broke down, choking back tears and struggling to hold herself together.

Eventually, the camera had to cut away as Kate Garraway began a link to another segment of coverage of the terror attack.

Kate could be heard telling Susanna that it was “okay” to be affected by the news, but an emotional Susanna said that there is “no use in getting upset” because the families of those killed in the attack were suffering so much more.

So far, 22 people have been confirmed dead and another 59 have been injured following the attack at Manchester Arena, which took place just after Ariana had finished her performance.
