Styles was set to perform at the Royal Arena nearby, but announced the show would no longer take place, citing the tragedy.
“I am devastated along with the people of Copenhagen. I love this city. The people are so warm and full of love,” Styles tweeted. “I’m devastated for the victims, their families and everyone in pain. I’m sorry we couldn’t be together. Please take care of each other.”
Styles’ next tour date is scheduled for Tuesday in Paris, France.
