This 28-page report calls on the US government to investigate the strike, publish its findings, and act in the event of wrongdoing. The December 12 attack killed 12 men and wounded at least 15 other people, including the bride. US and Yemeni officials said the dead were members of the armed group Al-Qaeda in the Arabian Peninsula (AQAP), but witnesses and relatives told Human Rights Watch the casualties were civilians. Obama said in a major address in May that US policy requires “near-certainty” that no civilians will be harmed in targeted attacks.
