The Gaza flotilla raid was a military operation by Israel against six civilian ships of the "Gaza Freedom Flotilla" on 31 May 2010 in international waters in the Mediterranean Sea. Nine activists were killed during the raid, while ten Israeli soldiers were wounded, one seriously. One further Turkish activist died later of his wounds. Three of the six flotilla ships, organized by the Free Gaza Movement and the Turkish Foundation for Human Rights and Freedoms and Humanitarian Relief (İHH), were carrying humanitarian aid and construction materials, intending to break the Israeli blockade of the Gaza Strip. Israel had warned the flotilla to abort their mission, describing it as a provocation. On 31 May 2010, Israeli Shayetet 13 naval commandos boarded the ships from speedboats and helicopters in order to force the ships to the Israeli port of Ashdod for inspection. On the Turkish ship MV Mavi Marmara, according to the Israel's own Turkel Commission, the Israeli Navy faced resistance from about 40 of the 590 passengers, including IHH activists – described in the commission's report as a separate "hardcore group" – who were said to be armed with iron bars and knives. According to flotilla organizer Greta Berlin, the Israeli soldiers did not start firing until an activist seized a gun from one of them. During the struggle, nine activists were killed, including eight Turkish nationals and one Turkish American, and many were wounded. On 23 May 2014, a tenth member of the flotilla died in hospital after being in a coma for four years. Ten of the commandos were also wounded, one of them seriously. According to a UN report, all activist deaths were caused by gunshots, and "the circumstances of the killing of at least six of the passengers were in a manner consistent with an extra-legal, arbitrary and summary execution." The five other ships in the flotilla employed passive resistance, which was suppressed without major incident. According to the UN report, several of the passengers were injured and the leg of one was fractured.
