Following Monday night’s terrorist attack at the Ariana Grande concert in Manchester, Warner Bros. has officially canceled the London premiere of Wonder Woman, the studio’s highly-anticipated superhero film — and the first in over 10 years to feature a female lead. The news comes just one day after British Prime Minister Theresa May elevated the terrorist threat level from “severe” to “critical,” and announced that another attack could be “imminent.”

Warner Bros. released an official statement to announce the cancelation of the Wonder Woman premiere, which was set to take place on May 31 in London with stars Gal Gadot, Chris Pine and Robin Wright in attendance along with director Patty Jenkins. In the statement, the studio expressed their sympathy for those affected by Monday night’s tragedy:

Our thoughts are with those affected by the recent tragedy in the UK. In light of the current situation, we will not be proceeding with our plans for the ‘Wonder Woman’ premiere and junket activities in London.

On May 22, a terrorist set off an explosive device at the Ariana Grande concert at Manchester Arena. The attack left 22 dead and around 59 injured, most of whom were teenagers and children. The suspect, who reportedly acted alone at the arena, died on the scene. The British police have since arrested three more suspects in connection with the attack. Grande has since suspended the remainder of her European tour, while Blondie and Take That have postponed their upcoming shows.

The British Red Cross partnered with the Manchester Evening News for a crowdfunding campaign to aid victims and their families. Over one million pounds have been raised so far. You can learn more and make a donation by visiting their official Just Giving page.
