The German authorities accused the young Syrian national authorities who support a foreign terrorist group through the foled conspiracy to attack the Taylor Swift concert in Vienna last August.
Mohamed A, which is described as a minor and still at large, accused of following the ideology of the Islamic State of Jihadist Group (is) and helping another suspect to prepare the attack.
The concert organizers called three sales gigs Taylor Swift before the first show in Vienna Ernst Dosegl Stadium last year, disappointing tens of thousands of fans during her tour at the time.
The authorities then arrested several suspects at the time, saying they appeared to be inspired by Al-Qaeda.
