Singer Ariana Grande has suspended her Europe tour indefinitely in the wake of a terrorist attack that took place at the end of her concert in Manchester. The explosion killed 19 people and injured several others, TMZ reported.

The “Dangerous Woman” singer has dropped her plans of performing in London on Thursday, according to sources. Following the tragic incident,  Grande tweeted:

"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," Scooter Braun, Grande’s manager, told TMZ.

Even though Grande was originally said to be physically “OK,” she is now reported to be in hysterics and is unable to carry on her tour which was scheduled to span across England, Belgium, Poland, Germany, and Switzerland.
