Methodology:

Mwatana for Human Rights has documented the civilian impact of the United States’ use of drones and other lethal force in Yemen for nearly a decade. Mwatana’s researchers—women and men dedicated to working towards peace and justice in Yemen—use rigorous and peer-reviewed investigation methods to investigate alleged incidents. They visit strike sites; interview survivors, family members, and witnesses; photograph weapons remnants; collect photographs and videos from relatives and community members; and examine documents that relate to witness accounts, including death certificates, birth certificates, medical reports, government and military statements, and other documents detailing where victims worked and studied, as well as the extent of harm they faced in these incidents. The significant body of evidence that informs this report was collected over a nearly four-year period.
