The demonstration, which took place in the Catalan capital, gathered several people to express their rejection of the Flotilla's interception. The event, initially peaceful, escalated to a point where incidents were recorded.

During the protest, some demonstrators were seen throwing objects, which prompted the intervention of police units. This situation led to charges to disperse the crowd and restore public order in the affected area of Barcelona.

The events occurred on May 1, 2026, a date that coincides with other mobilizations and news of interest in the region, such as the warning from CCOO and UGT about possible mobilizations for salary improvements or the intensification of pressure from the Mossos d'Esquadra against organized crime in the Girona regions.
