Manchester, England police are treating what happened at Ariana Grande's Monday night concert as a "terrorist incident" until they have reason to believe it's something else. Twenty-two are dead and approximately 50 injured after two explosions were reported at the Manchester Arena as Grande's concert was wrapping up.

Greater Manchester Police released the following statement on Facebook: "Emergency services are currently responding to reports of an explosion at Manchester Arena. There are a number of confirmed fatalities and others injured. Please AVOID the area as first responders work tirelessly at the scene."

The crowd was made up of mostly young people who had come out to see Ariana's first of three scheduled dates in the UK. One concertgoer, Ivo Delgado, told CNN: "It was a really big explosion. Everybody started screaming and running. There were people on the floor ... There was a lot of confusion."
