Forces from Ethiopia’s Amhara region, backed by federal troops, carried out systematic, ethnically targeted attacks on neighboring Tigray that amounted to humanitarian and war crimes, Amnesty International and Human Rights Watch said.

Abuses inflicted on the Tigrayans included murder, torture, rape and sexual slavery, said the two rights groups in a 240-page report released Wednesday. The findings are based on interviews conducted between December 2020 and March this year with more than 400 survivors.

"Amhara regional officials and regional special forces and militias, with federal forces’ complicity, are responsible for the ethnic cleansing of Tigrayans from Western Tigray,” the document states.
