“The United Nations counterterrorism chief said Europe faces a more acute threat from ISIS-K, the Islamic State affiliate to whom a 19-year old man pledged allegiance before plotting to terrorize Taylor Swift's concertgoers in Vienna this week. Vladimir Vorokov, the UN undersecretary for counterterrorism, said Thursday the ISIS-K threat, "regrettably," has "become manifest" in Vienna, where three of Swift's concerts were canceled when Austrian authorities arrested three suspects, and that the ISIS satellite is increasing in strength and influence. "The group is considered the greatest external terrorist threat to the continent," Vorokov told the UN Security Council, citing its "intensified" recruitment efforts and array of financial and logistical nodes.”
