Humanitarian aid transported by the second flotilla organized by Greta Thunberg is unlikely to reach Gaza due to unavailable docking facilities and Israel’s “lawful” blockade, according to a maritime expert.

As the boats departed from Barcelona on Sunday, Thunberg was accompanied by notable figures, such as Game of Thrones actor Liam Cunningham and former Barcelona mayor Ada Colau.

The Global Sumud Flotilla, comprising approximately 70 boats, aims to deliver food, water, and medicine to the people in the Gaza Strip. 

The flotilla is expected to be joined by more boats before they reach Gaza around Sep. 14 or 15.

Professor Kraska pointed out that Israel’s blockade is a lawful operation designed to prevent vessels from entering during an armed conflict, provided it fulfills criteria like giving notice, being effective, and enforcing impartially.

“Ultimately, Israel has the authority to uphold the blockade,” Kraska stated. “However, it’s not solely about the law — political and practical factors also play a role. Both sides are considering these aspects.

Israel, nonetheless, insists that its maritime security measures, resembling a blockade, are legitimate acts of war, entitling them to stop ships from anchoring.

“There is not one controlling narrative: there is international law, the political situation and the tactical dimension,” he added.
