Germany has charged a Syrian juvenile with supporting a foreign terrorist organization for helping to plan a foiled attack on a Taylor Swift concert in Vienna last year, the prosecutor general said in a statement on Friday.

The arrest comes nearly a year after the thwarted plot forced Swift to cancel three Eras Tour concerts in Vienna.

The youth, a Syrian who lives in Germany, was accused of helping to interpret bomb-building instructions and of translating an oath of allegiance to the Islamic State for the main suspect.
