Ariana Grande reacts to bombing outside Manchester arena following her concert

Ariana Grande took to Twitter early on Tuesday morning to react to the devastating bombing that killed at least 22 people after her Monday night concert in Manchester, England.

The singer had concluded her concert at the arena in Manchester when a suspected suicide bombing detonated just outside as thousands of fans left the show. The alleged act of terror killed at least 22 people -- a count that includes children -- and injured at least 60 others.

The concert was just one of many tour stops for Grande on her successful Dangerous Woman Tour to promote her album, Dangerous Woman.

Prime Minister Theresa May called the massacre a sickening act that targeted children, young people and their families. Police indicated on Tuesday that they knew the identity of the suspected 23-year-old man who carried out the attack.

UPDATE: According to TMZ, Ariana Grande has suspended her Dangerous Woman Tour indefinitely following the bombing in Manchester. She had been scheduled to perform upcoming shows throughout Europe in upcoming weeks, including a canceled show in London on Thursday night.

TMZ had previously reported that Grande is "in hysterics" after the tragic event and is inconsolable.
