The Palmer report was published on 2 September 2011 after being delayed, reportedly to allow Israel and Turkey to continue reconciliation talks.
On , a tenth member of the flotilla died in hospital after being in a coma for four years.
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.
Eiland's report found that the naval commandos had carried out their duties with professionalism, bravery and resourcefulness, and the commanders had exhibited correct decision making. A separate investigation was conducted by the United Nations Human Rights Council.
The report further determined, "the use of live fire was justified and that the entire operation was estimable." In August 2010, United Nations Secretary-General Ban Ki-moon announced that the U.

'We killed nine people and are sorry' – of course it sounds ridiculous. According to the National Post, Israeli deputy defense minister Matan Vilnai hinted that Israel had exhausted covert means of stalling the vessels. I don't want to elaborate beyond that, because the fact is there were not up to 10, or however many ships were [originally] planned." According to UPI press coverage, the officer alluded to "grey operations" against the flotilla and said that no such action had been taken against the Mavi Marmara out of fear that the vessel might be stranded in the middle of the sea, endangering the people on board.
