WIENER NEUSTADT, Austria, April 29 -- A 21-year-old accused of planning an Islamist attack on a Taylor Swift concert in Vienna in 2024 that was foiled at the 11th hour pleaded guilty as his trial opened on Tuesday. The defendant, an Austrian identified as Beran A, was arrested on August 7, 2024, the day before the first of three planned concerts by the US pop star in Vienna. All three dates were then cancelled. The trial is being held in Wiener Neustadt, near Vienna. Beran A is also accused, along with Slovak national Arda K, of planning attacks in the Middle East they did not go through with, and of providing moral support to a third man who has been arrested on suspicion of carrying out a knife attack in Mecca. reuters...
