The fate of about 1,300 Yazidi children in Iraq remains unknown 10 years on the Islamic State (ISIS) genocide in Sinjar (Shengal) in northern Iraq, Save the Children said on Thursday. 

Save the Children said out of the 1,300, about 300 to 400 of the children are likely still under 18, adding that about 2,000 children have been rescued so far, according to Nadia’s Initiative. 

In August 2014, ISIS attacked the Yazidi community in Iraq, killing more than 3,000 Yazidi men, women and children, and abducting at least 6,800 primarily women and children, according to the Amnesty International.

ISIS was territorially defeated in March 2019 by the Syrian Democratic Forces (SDF) supported by the U.S.-led Global Coalition.

The SDF managed to free hundreds of Yazidis in Syria after ISIS’ defeat in its last stronghold in the town of Baghuz in Deir ez-Zor Governorate, eastern Syria. However, many remain missing. 

According to Save the Children, ISIS killed, captured and displaced all 400,000 Yazidi people living in Sinjar on Aug. 3, 2014.

About 10,000 Yazidis were killed or abducted, half of all those executed were children, according to a report by multi-national researchers in the journal PLoS Medicine.

“Nearly all (93%) of those who eventually died on Mount Sinjar from injuries or lack of food and water were also children,” the organization added. “Of the around 6,400 abducted Yazidis, it’s estimated about half were children, according to the Yazidi-led nonprofit Nadia’s Initiative.”
