Austrian authorities have detained two suspects planning a terror attack at Taylor Swift concerts. Bomb-making materials were found at the home of the main suspect, a 19-year-old Austrian citizen, who confessed to the plot inspired by Islamic State and al-Qaeda. The suspect aimed to kill himself and many others using knives and explosives. A second suspect, a 17-year-old with Turkish-Croatian roots, was arrested, having recently been employed at the concert venue. A 15-year-old Turkish citizen was also questioned. Both primary suspects were known to the police and involved in the attack's preparation.
