Humanitarian Flotilla Departs Barcelona For Gaza As Activists Mobilize Against Israel's Aid Blockade

BARCELONA, SPAIN - AUGUST 31: Greta Thunberg (R) gestures to people while sailing on the Flotilla boat on August 31, 2025 in Barcelona, Spain. Activists, including Swedish campaigner Greta Thunberg, are departing Barcelona for Gaza as part of the Global Sumud Flotilla (GSF), a self-described "nonviolent humanitarian mission responding to the ongoing genocide and siege against the Palestinian people." The flotilla, which will be joined by others launching from various locations on September 4, includes activists, seafarers, doctors, and artists from over 40 countries. Thunberg and other crew members of a flotilla that attempted to reach Gaza after departing Italy in June were intercepted by Israeli forces and deported back to their countries of origin.
