1/11 Misinformed claims are circulating about the legality of Israel’s interception of the “Global Sumud Flotilla” on 30 April 2026.
2/11 The UN Secretary-General’s Palmer Panel concluded in 2011 that Israel’s naval blockade of Gaza was a legitimate security measure and complied with international law. unispal.un.org/pdfs/GazaFloti…
3/11 Under the San Remo Manual, vessels breaching or attempting to breach a lawful blockade may be captured. Where vessels resist capture after warning, further enforcement measures may follow. The Flotilla publicly stated that its mission was to “break Israel’s illegal siege”. iihl.org/wp-content/upl…
4/11 A vessel does not become immune from blockade enforcement merely because it says it is carrying humanitarian aid.
5/11 San Remo para 103 protects humanitarian passage only where the civilian population is “inadequately provided” with essentials. Aid is currently entering Gaza at scale under UNSC Res. 2803. The population is adequately provided with essentials, so this condition is not met.
6/11 The protection is also conditional on acceptance of inspection. Israel offered to receive genuine humanitarian aid at Ashdod for inspection and onward transfer to Gaza. That offer was declined by the Flotilla.
7/11 Claims that interception outside territorial waters is automatically unlawful are wrong. Freedom of navigation is not absolute; it is exercised subject to other rules of international law, including the law of naval blockade.
8/11 Nor is there a fixed maximum distance for enforcement. San Remo para 96 says the force maintaining a blockade “may be stationed at a distance determined by military requirements.” These requirements depend on operational circumstances.
9/11 The April 2026 fleet comprised around 58 vessels & 1k participants (2x Oct 25 flotilla). Interception as it progressed closer to Gaza would have presented significant operational risk.
10/11 Nor is this “piracy” as defined in international law. UN Convention on the Law of the Sea (UNCLOS) Art. 101 concerns acts committed “for private ends” by a “private ship”. State navies enforcing a declared blockade on State orders do not fit that definition. un.org/depts/los/conv…
11/11 Conclusion: it is lawful for a State’s navy to intercept vessels publicly declaring intent to breach a lawful blockade. Read the full briefing note: uklfi.com/wp-content/upl…. Watch the video: youtube.com/watch?v=Lrk2HX…
