TEL AVIV, Israel — Israeli naval forces intercepted the last boat in the Global Sumud Flotilla in the Mediterranean Sea near the Gaza Strip, ending an activist-led effort to deliver aid and challenge Israel’s naval blockade, organizers and Israeli officials said. The vessel was boarded and escorted toward the Israeli port of Ashdod as Israel said it was enforcing a lawful blockade in an active combat zone, while flotilla organizers denounced the seizure as illegal, Oct. 3, 2025.
The boat, named Marinette, was stopped about 42.5 nautical miles (79 kilometers) from Gaza, according to organizers. Israeli army radio said the navy took control of the vessel and detained those on board before leading it to port.
By Friday, organizers said Israeli forces had intercepted all 42 vessels in the flotilla. The broader convoy had drawn international attention for its size and its passenger list, which included climate activist Greta Thunberg, lawmakers and other public figures. Israeli authorities said those detained were safe and would be deported, with the process already underway for some passengers.
Global Sumud Flotilla: What happened in the Mediterranean
Organizers described the flotilla as a civil society mission meant to spotlight Gaza’s humanitarian crisis and press for a “people-led” aid corridor by sea. Israeli authorities, meanwhile, framed the mission as a political provocation and said it risked entering a restricted area while Israel remains at war with Hamas.
In earlier phases of the interception, activists and news reports described Israeli naval vessels approaching multiple small boats in international waters and using measures such as warnings, communications disruption and, in some cases, water cannons. Israel’s Foreign Ministry has said the boats were warned they were nearing an active combat zone and that any aid should be delivered through established channels.
The seizure of Marinette followed a larger operation in which most of the flotilla’s boats were stopped and hundreds of participants detained. Italy’s foreign minister said some boats would be towed to Ashdod and that deportations would follow.
Israel says the blockade is legal; activists call it unlawful
Israel argues its naval blockade is a legitimate security measure intended to prevent weapons smuggling into Gaza. Officials have also alleged that some flotilla organizers have ties to Hamas — accusations the activists reject.
Human rights groups dispute Israel’s position and say stopping civilian boats in international waters — particularly those carrying humanitarian supplies or medical personnel — violates international law. Amnesty International, responding to the detentions, called for the crew members to be released and warned against mistreatment, describing the interception as a “calculated act of intimidation.”
The dispute also sits within a wider debate over the blockade itself and aid access to Gaza, where the war that began after Hamas’ Oct. 7, 2023, attack has driven repeated warnings from international agencies about hunger, displacement and the breakdown of basic services.
Diplomatic fallout and what happens next
Governments with citizens on board reacted sharply in the days leading up to and following the interceptions. A Sept. 16 joint statement by foreign ministers from a group of countries — including Türkiye, Brazil, Colombia, Ireland, Malaysia, South Africa, Spain and Thailand — urged everyone to avoid “any unlawful or violent act” against the flotilla and warned that violations of international law, including attacks in international waters or illegal detention, could trigger accountability.
Even as the final boat was taken into custody, organizers said additional vessels were still attempting to reach Gaza, underscoring what both sides have described as a continuing flashpoint: activists seeking to break the blockade by sea, and Israel vowing to prevent unauthorized crossings.
