By forcibly intercepting and blocking the Madleen, Israel has once again ignored its legal obligations towards civilians in the occupied Gaza Strip. The crew were unarmed activists and human rights defenders on a humanitarian mission. They must be released immediately and unconditionally. They must also be protected from torture and other ill-treatment. As the occupying power Israel has an international obligation to ensure civilians in Gaza have sufficient and safe access to food, medicine, and other supplies indispensable to their survival. Instead, and as part of its calculated effort to inflict on Palestinians in Gaza conditions of life designed to bring about their physical destruction, it has consistently and deliberately impeded the provision of impartial humanitarian assistance for civilians in desperate need. During its voyage over the past few days the Madleen’s mission emerged as a powerful symbol of solidarity with besieged, starved and suffering Palestinians amid persistent international inaction. However, this very mission is also an indictment of the international community’s failure to put an end to Israel’s inhumane blockade. Activists would not have needed to risk their lives had Israel’s allies translated their rhetoric into forceful action to allow aid into Gaza. States must act now or risk complicity in Israel’s grave violations of Palestinians’ rights.
