An Iraqi 18-year-old who "took an oath of allegiance" to the Islamic State terrorist group just days ago is now the third suspect to be arrested in connection to a foiled plot to attack now-canceled Taylor Swift concerts in Austria, officials say.
Austrian Interior Minister Gerhard Karner said the individual "comes from the social environment" of the 19-year-old main suspect – an Austrian with North Macedonian roots who allegedly had bomb-making materials, chemical substances and technical devices at his home.
