Israel Intercepts Global Sumud Flotilla, Detaining Activists Including Ada Colau and Greta Thunberg

Global Sumud Flotilla Intercepted Off Gaza Coast

Israeli naval forces on Wednesday, October 1, 2025, began intercepting the Global Sumud Flotilla, a large convoy of vessels attempting to deliver humanitarian aid to the besieged Gaza Strip. The interception, which continued into Thursday, October 2, 2025, occurred approximately 70 nautical miles off the coast of Gaza, in what the flotilla organizers assert are international waters. The mission involved nearly 50 boats and an estimated 500 activists from over 45 countries.

Among the prominent figures detained were former Barcelona mayor Ada Colau, Swedish climate activist Greta Thunberg, European Parliament member Rima Hassan, and Mandla Mandela, grandson of Nelson Mandela.

Activists Report Harassment and Illegal Boarding

Activists on board the Global Sumud Flotilla reported aggressive tactics by Israeli forces. These included warnings to change course, the use of water cannons, and the jamming of communications, which caused live video streams from the vessels to go dark. The flotilla organizers described the actions as 'active aggression' and 'illegal interception and harassment,' stating that one ship, the Florida, was deliberately rammed, and others were attacked with water cannons. They maintain that the interception in international waters constitutes a violation of international law.

The flotilla's primary objective was to break Israel's blockade of Gaza and deliver critical humanitarian aid, including:

• Medical supplies
• Dry food
• School equipment
• Baby formula
• Diapers
• Prosthetic limbs

Organizers emphasized that the mission was also a non-violent protest to challenge the blockade and draw attention to the humanitarian crisis in Gaza, where a famine has been declared.

Israeli Response and International Condemnation

The Israeli Foreign Ministry confirmed the detention of activists, stating that the operation was 'safe' and that those detained were 'safe and in good health.' They are being transferred to Ashdod port for processing and eventual deportation. Israel dismissed the flotilla as a 'provocation,' asserting that the area is an 'active combat zone' and that the mission's true purpose was not humanitarian.

The interception has drawn widespread international condemnation. Protests erupted in major cities globally, including Rome, Istanbul, Athens, Buenos Aires, Madrid, and Barcelona. The Spanish government, through its Foreign Minister Jose Manuel Albares, summoned the Israeli charge d'affaires to convey its condemnation and to ensure the safety and rights of Spanish citizens on board. Spain's Prime Minister Pedro Sánchez had previously defended the mission as humanitarian. Colombian President Gustavo Petro responded by expelling Israeli diplomats and canceling a free trade agreement with Israel, while South African President Cyril Ramaphosa also condemned the action. Italy's largest union called for a one-day general strike in protest.

Background of the Global Sumud Flotilla

The Global Sumud Flotilla, a coalition of four major movements, including the Freedom Flotilla Coalition, had set sail from the Spanish port of Barcelona approximately a month prior. The mission aimed to establish a nautical humanitarian corridor, following previous unsuccessful attempts to break the blockade earlier in the year. Organizers had reported earlier incidents, including suspected drone attacks on some of their vessels during the voyage.
