This is all so tragic.

Ariana Grande has suspended her Dangerous Woman world tour in the wake of last night's terror attack at her Manchester concert, TMZ reports. The singer was set to perform in London on Thursday but is said to be "hysterical" over the incident, which claimed the lives of 22 fans and left 119 injured.

"Tonight, our hearts are broken. Words cannot express our sorrow for the victims and families harmed in this senseless attack. We mourn the lives of children and loved ones taken by this cowardly act. We are thankful for the selfless service tonight of Manchester's first responders who rushed towards danger to help save lives. We ask all of you to hold the victims, their families, and all those affected in your hearts and prayers," Grande's manager Scott Braun wrote on Twitter.

ISIS has claimed responsibility for the bloodshed, the Associated Press reports. Authorities have identified the suicide bomber, who died at the scene after detonating a "sophisticated" homemade device in the foyer of the arena.

What is the world coming to? This makes our heart hurt.
