A suicide bombing at an Ariana Grande concert in Manchester, England left 22 people dead and more than 50 others injured Monday. Now, fans of Justin Bieber are reportedly begging the singer-songwriter to cancel his British tour dates amid fear that a similar bombing could occur again.

The commitment of Bieber’s fan base, colloquially referred to as “Beliebers,” has been widely reported on over the course of his career. The singer’s “Purpose Tour” has upcoming shows planned in Cardiff June 30 and London July 2. And in the wake of Monday’s horrific event, fans have flooded the social media feeds of Bieber and Scooter Braun — who manages both of the 23-year-old pop stars — to request that they cancel his upcoming United Kingdom tour leg.

The requests can be found peppered into the comments section of Braun’s Wednesday Instagram post that depicted a black awareness ribbon with Grande’s signature bunny ears.

“Please,” wrote user zuzanka_je_bozi, “Justin mustn't go to London!”

Another user, marhrukhh, wrote, “Cancel Justin's concert in the UK, please. We want him to be safe, please.”

The pleas from worried fans can also be seen in responses to a tweet Braun posted Monday regarding the attack. The statement read, “Tonight, our hearts are broken. Words cannot express our sorrow for the victims and families harmed in this senseless attack.” Commenters were quick to jump at the chance to voice their concern about Bieber’s safety.

A representative for Bieber did not immediately return International Business Times’ request for comment about whether any cancellations will occur. However, it doesn’t immediately appear that any of Bieber’s dates will be rescheduled or canceled. Braun used a series of tweets Wednesday to assure fans that “fear cannot rule the day.”

“More people die each year from car crashes then terrorism,” he continued. “Yet I will get in my car. I will choose to live then to be afraid. So Manchester I stand with you. Jakarta I stand with u..children of Syria I stand with you. We will honor you by not giving in to the darkness.”

He added, “Am I angry? Hell yes. But how will we respond? With everything you think you took from us... love and joy and life!”

The alleged suicide bombing that occurred at Grande’s Monday evening concert forced the singer to suspend her “Dangerous Woman” tour indefinitely. Fans have rallied around the singer, who wrote on Twitter Monday that she was “broken.” She added, “From the bottom of my heart, I am so so sorry. I don’t have words.”
