The Global Sumud Flotilla organized the international maritime initiative that aims to break through Israel's naval blockade of Gaza and provide aid to the war-torn territory. The Global Sumud Flotilla told CBS News that on the night prior to the attack, Portuguese lawmaker Mariana Mortágua was on board. The Global Sumud Flotilla said at least 13 explosions were heard on and around several flotilla boats and objects were dropped on at least 10 boats, causing damage. A State Department official told CBS News that the department was monitoring the situation and is committed to providing assistance to U.S. citizens. Two Americans sailing with the Global Sumud Flotilla include Marine Corps veteran Jessica Clotfelter and Greg Stoker, organizer of the veterans' delegation to the group.
