A planned terrorist attack targeting Taylor Swift's concerts in Vienna was foiled thanks to intelligence provided by the CIA, which alerted Austrian authorities about the threat from an ISIS-connected group. CIA Deputy Director David Cohen revealed that the suspects, three teenagers aged 17 to 19, intended to kill 'tens of thousands' of concertgoers during the events scheduled for August 8-10, prompting their cancellation. Investigators found chemical substances and devices in the main suspect's home, indicating a serious threat involving knives or homemade explosives. Swift expressed her devastation over the cancellations but expressed gratitude that the authorities' actions prevented potential loss of life. The incident has raised discussions in Austria about expanding surveillance powers for intelligence agencies to monitor messages on smartphone apps, as current laws limit their capabilities. The suspects' lawyer claimed the allegations were exaggerated to justify new surveillance measures.
