An explosion blasted through Manchester Arena - Britain's largest indoor venue - on Monday evening at an Ariana Grande concert, killing at least 22 people and injuring 59 others.
The so-called Islamic State (Daesh) claimed responsibility for the attack, which was carried out by 22-year-old Salman Abedi, who was born in Manchester to Libyan parents.
That link to the Middle East has triggered Islamophobes around the world, especially on social media.
It started with this ...
Hours after the attack in Manchester, Twitter user @hannawwh tweeted out a heartfelt message to those affected.
"I can't believe it, I'm heartbroken. I'm so sorry to all the families who have lost loved ones and to all those injured," the tweet read.
Then a Twitter troll decided to hack the conversation with an extremely Islamophobic comment
Her response?
Muslim leaders condemned the attack, but the outpouring support from the Muslim community did not stop there.
Muslim taxi drivers, alongside Sikh taxi drivers, arrived to the scene of the attack soon after, offering victims rides to their destinations.
"It was a Muslim taxi driver that got me out of that hellish situation and to safety. People need to watch their words," Twitter user @L_Hurst wrote.
Others launched a crowdfunding campaign - led by the British Muslim Heritage Center - in an effort to raise money for the families of those affected.
The campaign titled "Muslims United for Manchester" has raised over 2,000 British Pounds at the time of writing.
