Greta Thunberg and 500 Activists Detained as Israeli Navy Seizes Gaza Aid Flotilla
Kieran Lockhart
When Greta Thunberg, the Swedish climate campaigner, and roughly 500 other activists, lawyers, parliamentarians and aid workers were boarded by the Israeli Navy on Wednesday, September 30, 2025, the world’s attention snapped back to the disputed maritime blockade around Gaza. The operation, announced by the Israeli Foreign Ministry, said the vessels were “safely stopped” and that all passengers were being transferred to an Israeli port. A Reuters‑verified video showing Thunberg surrounded by armed soldiers quickly went viral, reigniting a heated debate over the legality of Israel’s naval restrictions.
Background to the Naval Blockade
Israel has maintained a naval cordon off the Gaza coastline since the 2007 Hamas takeover, arguing that the seal is essential to prevent weapons smuggling. Critics, including the United Nations Office for the Coordination of Humanitarian Affairs, label the blockade a form of collective punishment that contravenes international humanitarian law. Over the past eight years, at least 20 civilian vessels have attempted to breach the zone, with varying degrees of success.
Legal scholars point out that a blockade is permissible only if it is publicly declared, applied impartially and does not deprive the civilian population of essential goods. The Sumud Flotilla—"sumud" meaning steadfastness in Arabic—was designed to test those very thresholds.
The Sumud Flotilla’s Route and Composition
The flotilla, organized by a coalition of European NGOs, set sail from the port of Limassol, Cyprus, on September 27. It consisted of 42 civilian boats, ranging from modest fishing skiffs to larger cargo‑type vessels, carrying an estimated 500 passengers and roughly 7,200 kilograms of food, medical supplies and winter clothing destined for hospitals in the Gaza Strip.
- Participants hailed from at least 15 countries, including Sweden, Germany, Brazil and South Africa.
- Among the passengers were three members of the European Parliament, twelve international human‑rights lawyers and five veteran humanitarian workers.
- The cargo included 2,400 meals, 150 kilograms of antibiotics and a portable dialysis unit.
According to the flotilla’s coordinators, the route was plotted to stay in international waters until within 50 nautical miles of Gaza, where they intended to request a safe‑passage corridor from the Israeli authorities.
The Interception on September 30, 2025
At approximately 07:45 UTC, Israeli naval vessels intercepted the flotilla about 70 nautical miles off the Gaza coast—well inside the 20‑nautical‑mile limit Israel says it enforces. Four armed patrol boats surrounded the lead ship, and boarding teams used fast‑ropes to climb aboard the smaller skiffs.
Eyewitnesses reported a relatively orderly process: “The soldiers shouted commands in Hebrew and Arabic. After a few minutes, the doors were opened and people were herded onto the deck,” one volunteer told Reuters. Thunberg was seen sitting calmly while soldiers checked her identification.
“We have carried out a lawful operation to enforce our security measures,” said Aviv Cohen, spokesperson for the Israeli Foreign Ministry. “All passengers are safe, and the humanitarian cargo is being inspected according to standard procedures.”
After the boarding, the vessels were escorted to the Israeli port of Ashdod, where officials began processing the detainees. The exact fate of the cargo remains unclear; Israeli sources claim it is being examined for any prohibited items before a decision on delivery is made.
International Reaction and Legal Debate
The interception sparked immediate condemnation from several European governments. The Swedish foreign ministry issued a brief note urging “prompt release of all detained individuals and transparent handling of humanitarian aid.” Germany’s ambassador to Israel called the boarding “unnecessary and escalatory.”
Human‑rights NGOs, including Amnesty International and Human Rights Watch, filed a joint statement asserting that the blockade constitutes a violation of the Fourth Geneva Convention. “Detaining civilians and humanitarian workers en masse, especially when they carry life‑saving aid, is clearly punitive,” the statement read.
Conversely, Israel’s defence ministry highlighted a recent intelligence report indicating that a small number of vessels were suspected of smuggling dual‑use items. “We cannot ignore the risk of weapons reaching Hamas,” a senior officer told a local news outlet.
Legal experts are divided. Professor Elena García of the International Law Institute in Madrid argues that the flotilla’s presence in international waters makes the boarding a breach of the United Nations Convention on the Law of the Sea (UNCLOS). Meanwhile, former Israeli navy commander Yossi Ben‑David maintains that “the blockade is a recognized security measure, and the interception was fully compliant with international law.”
What Comes Next for the Detainees and Aid
As of the afternoon of September 30, all 500 detainees were being held at a temporary processing center in Ashdod. Reports indicate that most have been allowed to make phone calls to their families, though access to legal counsel is limited.
International monitors from the Red Cross have requested permission to visit the detainees, a plea Israel has not yet answered. The United Nations Security Council is expected to hold an emergency meeting early next week to discuss the incident and the broader humanitarian situation in Gaza.
If the cargo passes inspection, Israel has said it could be delivered through the Rafah crossing under strict supervision. However, given the volatile security climate, many analysts predict further delays, leaving Gaza’s 2.3 million residents waiting for aid that is already on the brink of spoilage.

Frequently Asked Questions
Why did Israel intercept the Sumud Flotilla in international waters?
Israel argues that its maritime blockade extends to 20 nautical miles, but it also claims intelligence indicated potential smuggling of prohibited items. The navy said the boarding was a lawful security action, even though the vessels were beyond the 20‑mile limit, a point that legal scholars contest under UNCLOS.
What happened to the humanitarian supplies on board?
The cargo is being inspected at the Ashdod port. Israeli officials have not confirmed whether the food, medicines and a portable dialysis unit will be allowed into Gaza, though they say any prohibited items will be confiscated.
How are the detained activists being treated?
According to statements from the Israeli Foreign Ministry, all detainees are safe and have access to basic needs. However, legal access is limited and families have reported delays in communicating with their loved ones.
What legal arguments are being made about the blockade?
Human‑rights groups cite the Fourth Geneva Convention, saying a blockade that deprives civilians of essential supplies is illegal. Israel counters that the blockade is a security measure allowed under international law, provided it is proportionate and non‑discriminatory.
Could this incident affect future aid missions to Gaza?
The interception is likely to raise the stakes for future humanitarian convoys. NGOs may seek more robust diplomatic guarantees, while Israel may tighten its maritime monitoring, potentially leading to even fewer successful aid deliveries.
