A suspected ISIS-linked plot to attack Taylor Swift's concerts in Vienna has been foiled by Austrian police, leading to the arrest of two men, including a 19-year-old who had pledged allegiance to ISIS. Authorities found various chemicals at the suspect's residence that could potentially be used to create explosives. The concerts, scheduled from Thursday to Saturday at the Ernst Happel Stadium, have prompted heightened security measures, although officials have not declared the events entirely safe. Police are still investigating for potential accomplices, but confirmed that a concrete threat has been averted. Concertgoers are advised to arrive early due to increased security protocols. The immediate risk has been minimized, but officials caution that a general threat remains.
