The Kizil massacre (Chinese: 克孜爾大屠殺) occurred in June 1933, when Uighur and Kirghiz Turkic fighters of the First East Turkestan Republic broke their agreement not to attack a column of retreating Hui Chinese soldiers and civilians from Yarkand New City on their way to Kashgar. An estimated 800 Chinese Muslim and Chinese civilians were killed by Turkic Muslim fighters.
