On Sept. 26, 2010, Jews for Justice send a boat, the Irene, sailing under a British flag, to Cyprus, on its way to Gaza, with humanitarian supplies. The boat was sent in the wake of an Israeli attack on a Turkish boat bound for Gaza in May 2010, killing nine activists on board.
The organization adds: "As well as organising to ensure that Jewish opinions critical of Israeli policy are heard in Britain, we extend support to Palestinians trapped in the spiral of violence and repression. We believe that such actions are important in countering antisemitism and the claim that opposition to Israel’s destructive policies is itself antisemitic. We cooperate with other organisations on specific issues without necessarily endorsing everything they do."
