Germany: Counter-protest dwarfs neo-Nazi march in Chemnitz
Far-right activists were met with scores of counter-protesters as they marched through Chemnitz on Saturday, marking ‘The Day of the German Future’. Around 250 neo-Nazi protesters marched through the city centre, carrying flags of Imperial Germany and shouting xenophobic slogans such as ‘Germany for Germans, foreigners out.’ The protest was countered by around a 1,300-strong rally who attempted to disrupt the march, even scuffling with the police at one point.
Translated from Dutch NOS radio today:
The German police raided this morning in 25 homes belonging to members of the so-called Reichsbürger movement. They are suspected of, eg, forging passports and driving licenses.
Members of the Reichsbürger movement do not recognize the current state in Germany because it was imposed by the Allies after World War II. …
In 2016, a Reichsbürger shot and killed a member of a German arrest team, and in 2017 police raided members of the group who were preparing attacks on Jews, asylum seekers and the police.
