Swedish activist Greta Thunberg set sail from Barcelona on September 1, 2025, with the Global Sumud Flotilla to deliver aid to Gaza amid a severe humanitarian crisis. Israeli officials have announced plans to detain her and other participants in harsh conditions reserved for terrorists if they try to breach the blockade.
This bold move comes as Thunberg joins hundreds of activists in what organizers call the largest effort yet to break Israel’s 18-year naval blockade of Gaza. The flotilla aims to bring food, medicine, and other essentials to Palestinians facing famine and ongoing conflict.
Thunberg’s Role in the Global Sumud Flotilla
Thunberg, known worldwide for her climate activism, has shifted focus to the Gaza crisis. She announced her involvement in August 2025, calling it a global uprising against the blockade.
The flotilla departed from Barcelona with dozens of boats, set to meet more vessels from Tunisia on September 4. Organizers say it includes activists from over 40 countries, all committed to delivering aid directly.
Participants include notable figures like actor Liam Cunningham from Game of Thrones and former Barcelona mayor Ada Colau. They plan to challenge the blockade peacefully, highlighting the dire needs in Gaza.
Thunberg stated that this mission builds on her June 2025 attempt, where she was detained. She emphasized the need for international action to address the famine affecting millions.
Israel’s Harsh Detention Threats
Israeli National Security Minister Itamar Ben-Gvir is leading efforts to prepare for the flotilla’s arrival. Reports indicate plans to hold detainees in facilities typically used for high-risk terrorists.
These conditions could include strict isolation and limited access to legal aid. Ben-Gvir described the activists as threats to security, vowing to stop any breach by any means.
This stance aligns with Israel’s long-standing policy to enforce the Gaza blockade, tightened since the October 2023 conflict escalation. Officials argue it prevents weapons smuggling, though critics say it worsens civilian suffering.
In response to the June flotilla, Israel intercepted the vessel in international waters, detaining and deporting crew members including Thunberg.
Experts note that such detentions could spark diplomatic tensions, especially with activists from multiple nations involved.
Recap of Thunberg’s June 2025 Flotilla Attempt
In June 2025, Thunberg joined the Freedom Flotilla Coalition on the vessel Madleen, carrying limited aid like baby formula and medical kits.
Israeli forces boarded the ship in international waters on June 9, using chemical sprays and detaining 12 people, including Thunberg and French MEP Rima Hassan.
The group was held briefly in Ramle before deportation. Thunberg called it a kidnapping, while Israel labeled it a lawful action against blockade breakers.
This incident drew global attention, with media outlets reporting on the clash and its implications for aid delivery.

The Ongoing Humanitarian Crisis in Gaza
Gaza’s population of over 2 million faces acute shortages due to the blockade and military actions. The United Nations reports that famine risks have escalated in 2025, with child malnutrition rates soaring.
Aid deliveries have dropped sharply, with only a fraction reaching those in need. Recent data from the World Health Organization shows over 500,000 people displaced in the past year alone.
The flotilla aims to spotlight these issues, carrying supplies to address immediate needs like food and healthcare.
International bodies have called for eased restrictions, but Israel maintains the blockade is essential for security amid threats from groups like Hamas.
| Aspect | Details |
|---|---|
| Population Affected | Over 2 million Palestinians in Gaza |
| Key Shortages | Food, water, medicine, fuel |
| Recent UN Estimate | 1.9 million displaced since October 2023 |
| Famine Risk | High in northern Gaza, affecting 70% of children under 5 |
| Aid Blocked | 80% of truck deliveries halted in 2025 |
Global Reactions and Potential Outcomes
World leaders and activists have mixed responses. Some European nations support the flotilla’s humanitarian goals, while others warn of risks.
Social media buzzes with support for Thunberg, with posts highlighting solidarity from 44 countries. Protests are planned worldwide to coincide with the voyage.
If intercepted, detentions could lead to legal battles and further strain Israel-Palestine relations. Analysts predict the flotilla might force renewed talks on aid access.
The mission ties into broader 2025 events, like Houthi statements after their leader’s death, adding to regional tensions.
