This image released by Human Rights Watch on Saturday, May 4, 2013 shows a vehicle burning after a raid by Iraqi security forces on a Sunni protest camp in a public square that killed scores in Hawija, Iraq on April 23. Human Rights Watch on Saturday urged Iraqi authorities to give a government committee charged with probing a deadly raid by security forces on a protest camp last week greater financial and political backing to investigate who is responsible for what it described as an apparently unlawful use of lethal force.(AP Photo/Human Rights Watch)
