The field research and investigations conducted by Mwatana confirm that in the nine Yemeni governorates at least 615 civilians were killed among whom 120 were women and 220 were children.

This report provides credible evidence that U.S. drone strikes have killed and injured civilians in Yemen. The nine case studies documented in this report provide evidence of 26 civilian deaths and injuries to an additional 13 civilians. The nine strikes examined in this report raise questions about the extent to which the United States is complying with international law. These questions are especially serious with respect to the January 23, 2013 strike on a civilian house containing 19 civilians in Silat al-Jarraah village and the September 2, 2012 strike in which 12 civilians, including three children and a pregnant woman, were killed.
