The Israeli Defense Forces (IDF) detained 175 activists on Wednesday, including 31 Spanish citizens. The group was part of a flotilla that had departed from Barcelona in mid-April.
Unrest in Barcelona
Following the seizure of the flotilla, protests broke out late Thursday night outside of Israel’s Consulate in Barcelona. Approximately 400 people participated in a coordinated march that began at Plaça de Sants.
During the demonstration, protesters shouted slogans including “Boycott Israel,” “Israel is not a country, It’s an occupation,” and “From the river to the sea, Palestine will be free.”
The event turned violent as masked protesters overturned 10 garbage cans and targeted the Mossos d’Esquadra (Catalan police) with bottles, fireworks, and smoke bombs. Police responded by charging the crowd using batons and riot shields.
Diplomatic and Political Fallout
Spanish Foreign Minister José Manuel Albares is currently maintaining contact with the flotilla’s organizers. He is too communicating with the foreign ministers of other nations whose citizens were aboard the ships.

Pablo Castilla, a spokesperson for the Global Sumud Flotilla in Catalonia, has accused the European Union of complicity in offensives against Iran and Lebanon. He further described the detained activists as having been “kidnapped by Israel.”
Castilla has called on the EU to condemn the seizure and implement a genuine arms embargo. He urged the union to break all relations with the country, stating that his generation will not witness the “genocide of the Palestinian people.”
Potential Next Steps
Depending on the outcome of the Foreign Minister’s discussions, there may be further diplomatic pressure applied to secure the release of the 31 Spanish citizens. This coordination could lead to a formal request for the activists’ return.
Given the intensity of the recent clashes in Barcelona, additional coordinated marches are a possible next step if the detained activists are not released. The EU may also face increased internal pressure to address the demands for an arms embargo.
