Earlier this month, a Berlin court received an indictment against a young Syrian national, referred to as Mohammad A., in accordance with German privacy regulations.

Federal prosecutors said in a statement that he is accused of supporting a foreign terrorist organisation and preparing a serious act of violence.

According to prosecutors, the suspect endorsed the Islamic State group’s ideology and, from mid-July to August of the previous year, he communicated with a young man in Austria who intended to carry out an attack at a Taylor Swift concert in Vienna.

He allegedly helped by translating bomb-building instructions from Arabic and organising online contact with an IS member abroad, among other things.

The suspect also allegedly gave his acquaintance in Austria the text for an oath of allegiance to IS, which the latter used to join the group.

He is not in custody, prosecutors said. The court must now decide whether to bring the case to trial and when.
