A 19-year-old Islamic State sympathiser planned a deadly suicide attack at a Taylor Swift concert in Vienna, the country's intelligence agency said on Thursday.
Austrian authorities detained two suspects on Wednesday for allegedly plotting to attack one of three Vienna concerts by the US star , which had been due to start Thursday.
All three dates were cancelled on Wednesday, leaving disconsolate 'Swifties' to gather in the Austrian capital.
The 19-year-old main suspect had confessed, saying he 'intended to carry out an attack using explosives and knives', domestic intelligence agency (DSN) head Omar Haijawi-Pirchner told journalists.
'His aim was to kill himself and a large number of people during the concert, either today or tomorrow,' he added. The concerts had been to run from Thursday to Saturday.
