Israeli Attack on Flotilla Violated the UN Convention on the Law of the Sea
On Thursday, April 29, Israeli military forces illegally attacked vessels of the Global Samud Flotilla (GSF) while they were sailing on the high seas. Israeli commandos unlawfully seized 21 boats and abducted 177 flotilla participants, according to Nicole Schellekens, a Belgian GSF land-support person.
On May 1, the BBC reported that Israel released all but two of the detained participants in Greece. Thiago Avila and Said Abu Keshek remain in Israeli custody, and Israel has stated that it is transporting them to its territory.
Schellekens passed on a report that 34 of the abductees were physically abused by Israeli commandos while protecting the two men. The 34 were hospitalized, and 4 of them remain in the hospital at Heraklion on the Island of Crete. See the video by Elly Van Reusel, a medical doctor on “Magic,” one of the 22 seized boats.
The GSF condemned Israel’s actions as an act of piracy and called for the immediate release those still held by Israel.
The flotilla was engaged in a legal and peaceful mission aimed at breaking the internationally condemned Israeli siege of Gaza—a siege that imposes collective punishment on Gaza’s civilian population. The mission seeks to end Israel’s illegal policy of starvation, a policy that stunts the physical and cognitive development of children.
The flotilla was necessary only because, after destroying farms and fishing boats, Israel restricted or closed all land routes for aid into Gaza, and governments worldwide have so far failed to use their legal and political powers to force an end to the illegal siege.
The U.S. government has gone further than any other nation in collaborating with Israel’s illegal assault on Gaza’s civilians—the US provides the funds, bombs, F-35 jets, and bulldozers, along with the diplomatic cover that grants the Israeli government impunity.
US states have done little. Rather than adopt human rights promoting purchasing and investment legislation, Vermont has gone so far as to train its Air National Guard with 115-decibel F-35 jets low over one of the state’s most densely populated cities, where political and military leaders knew the flights would cause suffering to working-class and ethnic minority children. This location was deliberately selected to prepare the unit to target civilians. It was foreseeable that the Trump Administration would call the Vermont F-35 unit up, first to bomb in Venezuela, and now poised to resume their bombing in Iran.
The Israeli Assault on the Flotilla Violated International Law
Although Israel is not a party to the United Nations Convention on the Law of the Sea (UNCLOS), the core provisions of the treaty are recognized as customary international law and are legally binding on all countries.
• Article 92 grants a vessel’s flag state exclusive jurisdiction, effectively making the vessel sovereign territory of that country. By boarding the flotilla’s vessels without permission, abducting passengers, and seizing the boats, Israeli commandos violated the sovereignty of each of the flag states.
• Article 87 guarantees freedom of navigation on the high seas. Freedom revoked by Israeli commandos.
• Article 110 specifically prohibits warship personnel from boarding a foreign ship on the high seas except under narrowly defined circumstances—none of which applied in this case.
• Article 88 reserves the high seas for peaceful purposes.
• Article 301 requires states to refrain from any threat or use of force against the territorial integrity or political independence of any state. Which includes the vessels of any state.
Israel violated all of these provisions.
Enforcement of the UN Convention on the Law of the Sea
Previous violations of the law of the sea have led to enforcement actions, including:
• Ordering the prompt release of vessels
• Awarding compensation
• Banning the perpetrator from accessing ports
• Freezing the perpetrator’s assets
• Restricting trade with the perpetrator
• Banning the transfer of military goods to the perpetrator
• Establishing a tribunal to investigate and prosecute those responsible
Enforcement Action Is Needed Now
Similar enforcement actions must be taken in response to Israel’s gross violations of the Law of the Sea. If flag states fail to act, they effectively grant impunity to the Israeli perpetrators, invite further violations, and they encourage even more extreme illegal actions by Israel.
Demand that your government officials take enforcement action now.
It would be nice to think that Israel will be held accountable for their piracy of the flotilla and for beating and arresting its members, but we all know that the UN will ignore this as a favor to the US and its allies. They only way we will ever hold them accountable is by dismantling the apartheid regime once and for all.
Thank you for this excellent and informative piece! I so wish I had found it before I sent out a Peace Bit message to the peace "lobbyists" for whom I write Peace Bit prompts each day. But if you would like to see it, it's here: https://kathleentemple.wordpress.com/2026/05/02/if-i-had-a-hammer-peace-on-may-2-2026/
Anyone: if you would like to receive a short "bit" of suggested wording each day for contacting your legislators in the cause of peace, just let me know. I'd be so happy to add your email address to my distribution. I haven't missed a day since I started over 4 years ago.
