Nearly 2,000 Yazidi children freed from the grips of the Islamic State group in recent years are still trapped by psychological and physical trauma, Amnesty International warned on Thursday.

In a new report based on dozens of interviews in northern Iraq, the rights group found that 1,992 children who faced torture, forced conscription, rape and other abuses at the hands of IS were not getting the care they need.

“While the nightmare of their past has receded, hardships remain for these children,” said Matt Wells, deputy director of Amnesty’s crisis response team.
