In the September 2011 Palmer Report, the UN investigative committee for the 2010 Flotilla to Gaza said that Israel's naval blockade of Gaza was legal under international law, but criticised the nature of the Israeli raid. Later that same month, five independent U.N. rights experts reporting to the U.N. Human Rights Council rejected that conclusion, saying the blockade had subjected Palestinians in Gaza to collective punishment in "flagrant contravention of international human rights and humanitarian law."
