Austrian authorities have foiled a terror plot targeting Taylor Swift's concerts in Vienna, leading to the cancellation of three sold-out shows that were expected to draw tens of thousands of fans. Two suspects, aged 19 and 17, were arrested after investigators discovered bomb-making materials and evidence of radicalization linked to the Islamic State group and al-Qaida. The 19-year-old, who had been planning the attack since July, aimed to maximize casualties using knives or homemade explosives, intending to strike outside the Ernst Happel Stadium. Concert organizers canceled the events for safety, acknowledging the potential risk to up to 65,000 concertgoers and 30,000 onlookers. Austrian Interior Minister Gerhard Karner confirmed that the attack was planned for the concert dates, but no tickets had been purchased by the suspects. The investigation continues, with authorities exploring additional links to the planned attack.
