A suspected terrorist attack killed at least 22 people and injured 59 people at an Ariana Grande concert in Manchester, United Kingdom, Monday night.
A suicide bomber detonated an improvised explosive device near an entrance to Ariana Grande’s concert in the Manchester Arena, which seats about 21,000 people.
According to the Greater Manchester Police Department, the explosion happened after Grande had performed her last song for the night and people were exiting the venue.
“We have been treating this as a terrorist incident,” Ian Hopkins, chief constable of the Greater Manchester Police, told NBC News.
Witnesses of the incident believe the suicide bomber used a nail bomb as reported by The New York Times and may have acted alone.
However, investigators are still trying to find out if he was a part of a wider network of terrorists.
“We are working to establish the full details of what is being treated by the police as an appalling terrorist attack,” British Prime Minister Theresa May said, following the attack. “All our thoughts are with the victims and the families of those who have been affected.”
Meanwhile, Ariana Grande was at a loss for words following the incident.
“Broken,” she wrote on Twitter. “From the bottom of my heart, I am so sorry. I don’t have words.”
Other celebrities have also poured their support and sympathies to the victims of the attack.
