What we know about Taylor Swift concert plot, other attacks
August 8, 2024August 2024: Taylor Swift concerts in Vienna canceled
Organizers have canceled three concerts by US pop star Taylor Swift slated for August 8, 9 and 10 at Vienna's Ernst Happel Stadium, due to a planned Islamist terror attack. Police had expected around 65,000 people to attend each of Swift's concerts and many fans had already arrived in the Austrian city.
Shortly after his arrest, a 19-year-old main suspect confessed that he had wanted to kill "a large number of people" at the concert by committing a suicide attack, Austrian security authorities said. Chemical substances and technical devices were seized from the man, who sympathized with the jihadis "Islamic State" (IS) militia. A 17-year-old was also arrested.
The arrests have reduced the concrete threat situation to a minimum, authorities have said, but an abstract threat and increased risk of terrorism has existed for months.
