Story highlights Former ISIS sex slave Nadia Murad seeks an investigation into the terror group's crimes

Murad was enslaved when ISIS fighters took over her village in Kurdistan in 2014

(CNN) A Yazidi woman who was kidnapped and taken as a sex slave by ISIS told CNN's Fareed Zakaria on Sunday that the Iraqi government and the UN should establish an investigation in order to bring members of the brutal regime to justice.

Nadia Murad, along with her counsel, international human rights lawyer Amal Clooney, described her ordeal to Zakaria. It began in 2014 after ISIS militants arrived at her village in Sinjar, Kurdistan, she said.

"Early morning on August 3, 2014, they attacked us," she recalled.

"Nearly 6,500 women and children from the Yazidi were abducted and about 5,000 people from the community were killed during that day. For eight months, they separated us from our mothers and our sisters and our brothers, and some of them were killed and others disappeared."

Murad's mother and six of her brothers and stepbrothers were executed. Murad, along with other unmarried women, was taken as a sex slave and passed around various ISIS militants.
