Overview
- The 21-year-old defendant, who went on trial Tuesday in Wiener Neustadt, acknowledged guilt for the Vienna concert plot and now faces a possible 10 to 20 years in prison.
- Prosecutors say he swore allegiance to the Islamic State group, learned IS-style shrapnel bomb methods, produced a small amount of the explosive TATP, and sought illegal firearms and a hand grenade.
- A co-defendant, identified as Arda K., also appeared in court and admitted traveling to Istanbul with intent to carry out an attack, while both men dispute encouraging a third associate.
- Authorities arrested the accused on August 7, 2024, searched his home, found bomb-making materials, and—after U.S. intelligence warnings—canceled three Taylor Swift shows scheduled to start the next day.
- Investigators link the case to a wider cell that discussed strikes in Dubai and Istanbul, and cite a related March 2024 stabbing of a security guard at Mecca’s Grand Mosque, with the Saudi suspect still in custody as proceedings continue next month.
