Over a period of three years, Islamic State militants trafficked thousands of Yazidi women and girls and killed thousands of Yazidi men;[13] the United Nations reported that the Islamic State killed about 5,000 Yazidis[5] and trafficked about 10,800 Yazidi women and girls in a "forced conversion campaign"[14][15] throughout Iraq. By 2015, upwards of 71% of the global Yazidi population was displaced by the genocide, with most Yazidi refugees having fled to Iraq's Kurdistan Region and Syria's Rojava.[16][17] The persecution of Yazidis, along with other religious minorities, took place after the Islamic State's Northern Iraq offensive of June 2014.[18][19]
Amidst numerous atrocities committed by the Islamic State, the Yazidi genocide attracted international attention and prompted the United States to establish CJTF–OIR, a military coalition consisting of many Western countries and Turkey, Morocco, and Jordan. Additionally, the United States, the United Kingdom, and Australia made emergency airdrops to support Yazidi refugees who had become trapped in the Sinjar Mountains due to the Islamic State's Northern Iraq offensive of August 2014. During the Sinjar massacre, in which the Islamic State killed and abducted thousands of trapped Yazidis, the United States and the United Kingdom began carrying out airstrikes on the advancing Islamic State militants, while the People's Defense Units and the Kurdistan Workers' Party jointly formed a humanitarian corridor to evacuate the rest of the Yazidi refugees from the Sinjar Mountains.[20]
The United Nations, and several other organizations, including the Council of Europe and the European Union, have designated the anti-Yazidi campaign by the Islamic State as a genocide,[1] as have the United States, Canada, Armenia, and Iraq.[1][10]
