The teenage gunman who murdered nine people in a mass shooting in Munich last week had far-Right sympathies and the killings may have been racially motivated, it has emerged.

Ali David Sonboly, who was born in Germany to Iranian parents, was proud he shared a birthday with Adolf Hitler and regarded himself as a pure “Aryan”, according to a new reports.

Police have found no links to any far-Right groups, and believe he was a lone gunman acting from personal motivation.

Initial suspicions the killings may have had a far-Right background were dismissed when it emerged that Sonboly was from an Iranian Muslim family.
