Scores of women and girls in Ethiopia’s northern Tigray region were sexually assaulted, often by multiple men alleged to be combatants, after a peace agreement last year ended the conflict there, according to a new study of medical records released on Thursday. The Tigray conflict killed hundreds of thousands of people and left untold thousands of women and girls with the trauma of sexual assault. At least 128 sexual assaults occurred after the peace agreement was signed last November, according to the study, which looked at records from the start of the conflict in November 2020 through June.
