Multiple independent sources confirm that Israeli forces intercepted vessels of the Global Sumud Flotilla. Reports include The Guardian, The Independent, and other news sources detailing the interception of vessels in international waters.

Evidence from Türkiye Today and other reports confirm that the Israeli navy boarded multiple vessels and detained activists. While the specific location 'off Cyprus' is implied by the maritime route and the general context of the interception in the Mediterranean, the act of boarding several vessels is explicitly reported by multiple sources.

The claim that over 50 boats were involved is supported by Türkiye Today, which mentions '23 of the flotilla's 52 vessels'. Additionally, other reports mention more than 30 vessels departing Crete toward Türkiye. The timeline aligns with the May 2026 date mentioned in the evidence.
