Organizers have canceled three Taylor Swift concerts in Austria after authorities said they foiled a terror attack planned for the Vienna leg of her blockbuster Eras tour.

From The CNN, the extraordinary decision – which could come at significant cost to Vienna’s businesses – has devastated fans and renewed focus on the vulnerability of huge concerts as soft targets for terror networks and spree killers.

Swift was scheduled to play three shows in the European city from Thursday to Saturday – which have all been canceled, according to Barracuda Music, the promoter for her concerts in Austria.
