Taylor Swift spoke out after canceling her Vienna Eras Tour shows due to the August concerts being the target of an alleged planned terror plot, telling fans she has a “tremendous amount of guilt.”

“Let me be very clear,” the Grammy winner explained, “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.”

Noting that her “silence” when it came to her Vienna tour stops—scheduled for Aug. 8, Aug. 9 and Aug. 10—was her “actually showing restraint and waiting to express yourself at a time when it’s right to,” Taylor continued, “My priority was finishing our European tour safely, and it is with great relief that I can say we did that.”

And Taylor credited the thousands of Austrian fans who gathered in the streets to sing her music anyway with inspiring her to make a few security changes behind the scenes for the U.K. concerts that followed.

“I was heartened by the love and unity I saw in the fans who banded together,” the 34-year-old said. “I decided that 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.”

Noting that her Eras Tour team “worked hand in hand with stadium staff and British authorities every day in pursuit of that goal,” Taylor expressed her appreciation for how well her remaining five tour dates at London’s Wembley Stadium turned out.

“London felt like a beautiful dream sequence,” the singer shared. “All five crowds at Wembley Stadium were bursting with passion, joy, and exuberance.”

Taylor added, “The energy in that stadium was like the most giant bear hug from 92,000 people each night, and it brought me back to a place of carefree calm up there.”
