Overview

• Organizers say roughly 50 boats from 44 countries are involved, with about 300–340 people departing Barcelona in small and mid-size vessels.
• The effort aims to deliver food and medical supplies and to open a maritime humanitarian corridor into Gaza in defiance of Israel’s naval blockade.
• Confirmed participants include Greta Thunberg, Susan Sarandon, Liam Cunningham and former Barcelona mayor Ada Colau, with additional boats set to join from ports such as Bizerte, Genoa and Catania.
• Exact sailing plans remain undisclosed after recent aid missions—the Conscience and the Madleen among them—were intercepted or attacked in 2025.
• Volunteers trained crews on international law and safety protocols as organizers describe the action as a nonviolent response to government failure.
