A 21-year-old Austrian man has gone to trial on charges of plotting an attack on Taylor Swift concerts. Prosecutors say Beran A. received training from Islamic State members on how to handle explosives. The trial marks the culmination of an investigation into an alleged jihadist plot targeting the pop star's European tour dates. Austrian authorities arrested the suspect earlier this year after intelligence agencies flagged his communications with extremist networks. The case underscores ongoing security concerns around high-profile events and the reach of terrorist recruitment operations across Europe. Details on the specific alleged targets and timeline remain limited as the trial proceeds.
