LOS ANGELES 鈥 US pop megastar Taylor Swift revealed on Wednesday that a 鈥渘ew sense of fear鈥 came over her after authorities uncovered a plot to attack her Vienna concert venue as well as guilt for letting down fans by canceling her three shows in the city.

鈥淭hanks to them, we were grieving concerts and not lives,鈥 Ms. Swift said on Instagram in her first public comments since news of planned attack surfaced two weeks ago.

Police in Austria who they said confessed to wanting to cause a 鈥渂loodbath鈥 at Swift鈥檚 Eras Tour shows.

鈥淗aving our Vienna shows canceled was devastating,鈥 Ms. Swift said. 鈥淭he 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.鈥

Ms. Swift said she decided 鈥渁ll 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.鈥

The London dates took place without incident , ending the European leg of the record-breaking Eras Tour.

The singer said she had not commented earlier because she did not want to risk provoking harm at future concerts.

鈥淟et 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,鈥 Ms. Swift wrote. 鈥淚n cases like this one, 鈥榮ilence鈥 is actually showing restraint.鈥
