Taylor Swift ends European leg of Eras tour with surprise-packed show

"Thanks to them, we were grieving concerts and not lives," Taylor said on Instagram in her first public comments since news of the planned attack surfaced two weeks ago. Police in Austria arrested a 19-year-old man who they said confessed to wanting to cause a "bloodbath" at Swift's Eras Tour shows.

"Having our Vienna shows cancelled was devastating," Taylor said. “The reason for the cancellations filled me with a new sense of fear, and a tremendous amount of guilt because so many people had planned on coming to those shows.” she said she decided “all of my energy had to go toward helping to protect the nearly half a million people I had coming to see the shows in London.”

The singer said she had not commented earlier because she did not want to risk provoking harm at future concerts. "Let me be very clear: I am not going to speak about something publicly if I think doing so might provoke those who would want to harm the fans who come to my shows," Swift wrote. "In cases like this one, 'silence' is actually showing restraint. and waiting to express yourself at a time when it's right to. My priority was finishing our European tour safely, and it's with great relief that I can say we did that,” she added.
