In Madrid, approximately 2,000 protesters gathered to demonstrate against the government on the anniversary of previous protests at the PSOE headquarters on Ferraz Street.
The protest, organized by the far-right group Núcleo Nacional, began at Plaza de España and moved through several streets, with participants chanting nationalist slogans.
The demonstration turned violent as some attendees burned containers and threw bottles at police, who responded with rubber bullets and dispersed the crowd.
Two individuals were arrested during the clashes.
The PSOE condemned the protest, labeling it a "black march" and criticizing the fascist chants and Nazi salutes.
They urged all democratic parties to denounce such movements, emphasizing that these actions threaten democracy, not just the PSOE.
