Tensions rose in Barcelona during the Diada celebrations, beginning with clashes between antifascist and left-wing independentist organizations and the far-right group Aliança Catalana. During a floral offering at the Fossar de les Moreres, approximately 3,000 people gathered, leading to police charges and multiple arrests after activists reportedly threw eggs at leader Sílvia Orriols.

Following these initial tensions, the unrest escalated into riots in central Barcelona. Protesters burned containers and threw objects at the Mossos d'Esquadra near Passeig de Sant Joan, Ronda de Sant Pere, and the Arc de Triomf. Police used batons to disperse crowds, and eight individuals were arrested for public disorder as the disturbances spread through several city intersections.
