The Simele massacre (Syriac: ܦܪܡܬܐ ܕܣܡܠܐ‎ pramta d-Simele, Arabic: مذبحة سميل‎‎ maḏbaḥat Summayl) was a massacre committed by the armed forces of the Kingdom of Iraq during a campaign systematically targeting the Assyrians of northern Iraq in August 1933. The term is used to describe not only the massacre in Simele, but also the killing spree that took place among 63 Assyrian villages in the Dohuk and Mosul districts that led to the deaths of between 5,000 and 6,000 Assyrians.
