BERLIN (Reuters) - An 18-year-old Iraqi national was detained in Vienna in connection with investigations into an alleged plot to strike a Taylor Swift concert in the Austrian capital, the interior ministry said on Friday.

The Iraqi national is said to have come from the same circle as the main suspect, a 19-year-old Austrian with North Macedonian roots, according to the ministry.
