Austrian police say the 19yo arrested for planning an attack at Taylor Swift’s Eras Tour concert in Vienna had previously pledged allegiance to the Islamic State terror group. Specifically, he “intended to carry out an attack using explosives and knives” to kill a large number of people and himself. The man they have detained is the main suspect – 3 others are still being tracked down. Swift was due to perform for at least 150,000 people this week but organisers said they had “no choice but to cancel” the 3 sold-out shows “for everyone’s safety”, and offered full refunds. Swift hasn’t made a statement herself, but the cancellation is notable because aside from COVID shutting down her 2020 tour, she’s only cancelled 1 show before. This all might bring to mind the 2017 Ariana Grande concert bombing in Manchester – Swift has said that’s her “biggest fear”.
