Troops and militias aligned with the Ethiopian government have subjected hundreds of women and girls to sexual violence in Ethiopia’s war-torn Tigray region, according to a new report by Amnesty International.

The report details widespread rape and sexual violence carried out by members of the Ethiopian National Defense Force (ENDF), the Eritrean Defense Force (EDF), the Amhara Regional Police Special Force (ASF), and Fano, an Amhara militia group. To conduct the report, Amnesty interviewed medical professionals and 63 survivors of sexual violence between March and June 2021.

Victims included children and pregnant women, according to the report. Twenty-eight survivors said Eritrean forces were the sole perpetrators of rape.

“Soldiers and militias subjected Tigrayan women and girls to rape, gang rape, sexual slavery, sexual mutilation and other forms of torture, often using ethnic slurs and death threats,” Amnesty International said in a statement on Wednesday.

“Given the context, scale, and gravity of the sexual violence committed against women and girls in Tigray, the violations amount to war crimes and may amount to crimes against humanity,” the report said.

The report also detailed “additional acts of brutality accompanying the rapes,” adding that medical professionals who have treated survivors of sexual violence in the region recounted seeing cases of nails and shrapnel used during sexual assaults.

CNN has contacted the Amhara regional government, Amhara’s head of peace and security, an ENDF spokesperson and the Ethiopian government for comment on the Amnesty report.

Agnès Callamard, Amnesty International’s Secretary-General, said in a statement that “it’s clear that rape and sexual violence have been used as a weapon of war to inflict lasting physical and psychological damage on women and girls in Tigray. Hundreds have been subjected to brutal treatment aimed at degrading and dehumanising them.”

“The Ethiopian government must take immediate action to stop members of the security forces and allied militia from committing sexual violence, and the African Union should spare no effort to ensure the conflict is tabled at the AU Peace and Security Council,” Callamard added.

CNN previously reported on evidence of sexual violence being used as a deliberate weapon of war in Ethiopia’s northern Tigray region.
