Ariana Grande suspends Dangerous Woman Tour after an explosion at her Manchester Arena concert Monday night.

The explosion, which is now treated as a terrorist attack, took place within the foyer area of the 18,000-person venue shortly after Grande left the stage. It killed 22 people and injured 59 others.

In light of the incident, the “Side To Side” singer is putting all of her European dates on hold “indefinitely”, TMZ reports. Grande was scheduled to perform in various European cities, including London, Antwerp, Zurich and Paris, in the next few weeks until June 17.

Grande is physically unhurt, but took to Twitter to express her sadness, saying, “broken. from the bottom of my heart, i am so so sorry. i don’t have words.”

The pop star and her team are reportedly deeply concerned about security, as most of Grande’s fan base is made up of teens and young people. Manager Scooter Braun said in a statement, “We mourn the lives of children and loved ones taken by this cowardly act,” adding, “We ask all of you to hold the victims, their families, and all those affected in your hearts and prayers.”
