The Austrian branch of the Identitarian movement - Identitäre Bewegung Österreich - took to the streets at the weekend in protest against refugees and immigrants, chanting slogans such as ‘Our Flag, Our Country'.
Between 800 and 1000 right-wing protesters from Austria, France, Germany and Italy clashed with a similar number of counter-protesters from anti-fascist and left-wing groups.
Before the march Identitäre had posted rules online for the participants to follow, including banning the showing of right-wing extremist tattoos and clothing.
Now the group say they are bringing a case against the ORF's main evening news broadcast Zeit im Bild for describing them as right-wing extremists and neo-Nazis.
“Patriots faced violence and murder attempts while exercising their democratic rights, to only then be insulted by politicians and media as neo-Nazis and right-wing extremists,” said their spokesperson Patrick Lenart.
Following the march, one member of the right-wing group was arrested for alleged neo-Nazi propaganda activity.
Thirteen people were injured during the clashes between left and right-wingers, including four police.
Seven of the left-wing protesters - who started throwing rocks, fireworks and bottles - were arrested for a variety of public order offences.
The march was the latest in a run of protests organised by the right-wing group.
A few days earlier the Carinthian branch of the group had stormed into a lecture on asylum at a university in Klagenfurt dressed up in burkas and middle-ages costumes.
The group then proceeded to carrying out a pretend ‘stoning' on a member who they said was dressed to represent an Austrian patriot.
Previous attacks have included throwing fake blood onto an audience watching a play performed by refugees, interrupting the play by unfurling a banner saying “multiculturalism kills”.
