September 2025 in Greece

The Global Sumud Flotilla, sometimes referred to as the Global Freedom Flotilla, was an international, civil society-led maritime initiative launched in mid-2025, which attempted to break the Israeli blockade of the Gaza Strip but was thwarted in an intercept by Israeli naval forces. It is named for ṣumūd, Arabic for 'steadfastness' or 'resilience'. The initiative emerged in July 2025, organised by coalition of Freedom Flotilla Coalition (FFC), Global Movement to Gaza, Maghreb Sumud Flotilla and Sumud Nusantara, during the Gaza war. The flotilla comprised over 40 vessels with 500 participants from more than 44 countries, making it the largest civilian-led convoy of its kind in history. Some attempts to break the Israeli blockade were successful before 2010, but since then ships have been intercepted or attacked by Israeli forces, including an attack by drones in May 2025 and interceptions in international waters in June and July 2025. By early 3 October, Israel had intercepted all vessels of the flotilla, after drone attacks had been reported, and naval vessels dispatched to provide assistance. The flotilla was the first unauthorized naval humanitarian mission to come within 70 nautical miles (130 km) of the Gaza coast since the imposition of the blockade in 2009.
