In August 2024, a terrorism plot by followers of the Islamic State, a jihadist militant group, targeting a concert of the American singer-songwriter Taylor Swift at the Ernst-Happel-Stadion in Vienna was uncovered and neutralised. Three males, aged 17, 18 and 19, were arrested in Austria for involvement in the plot that was intended to mass murder concert attendees as well as onlookers in the stadium vicinity; a juvenile male in Germany was charged in 2025 for aiding those in Austria.
