This February 2017 video says about itself:
The release of a video of a neo-Nazi rock concert in 2005 attended by the leadership of Golden Dawn in Greece has grabbed headlines and is proving a major blow to the fascist party, which is on trial for constituting a criminal organisation.
Translated from Dutch NOS TV today:
Extreme right-wing activists violently attack Greek MP
In Greece a member of parliament has been beaten up by probably dozens of extreme right-wing activists. He was taken to the hospital injured.
The victim, 40-year-old Petros Konstantineas of the left-wing government party Syriza, was attacked after visiting a football match in the city of Kalamata with his son. A party member says to Greek media that it concerned about thirty extreme right-wing perpetrators.
Greek political parties have reacted with horror to the attack. Prime Minister Tsipras, also of Syriza, says that the “fascists” who attacked Konstantineas will be tried. The police have now arrested five suspects.
The injuries of the victim are not serious. He may probably be discharged from the hospital soon.
Konstantineas is a fairly well-known member of parliament, partly because of his previous career as a professional football referee. He has been in parliament since 2015.
