A former Islamic State (Isis) sex slave, Nadia Murad, was on Friday appointed as United Nations' Goodwill Ambassador for human trafficking.

The 23-year-old has also been nominated for the Nobel Peace Prize this year. She was a teenager when Isis militants attacked her village in Iraq in 2014. Nadia was from a non-Muslim Yazidi community and had to suffer many atrocities.

Nadia saw her father and brother being killed in front of her eyes. She was then abducted by Isis and made to work as a sex slave. Nadia later managed to escape the nightmare and sought refuge in Germany.

"During her Ambassadorship, Nadia will focus on advocacy initiatives and raise awareness around the plight of the countless victims of trafficking," the formal UN announcement stated.

She has been selected to become the Goodwill Ambassador for the Dignity of Survivors of Human Trafficking by United Nations Office on Drugs and Crime (UNODC).

Nadia had addressed the UN Security Council in 2015 and talked about her ordeal in the Isis captivity. She said that being a sex slave for Isis, she was put under a kind of torture that 'a mind could not imagine'. She said that the 'slaves' were made to pray before they were gang-raped and were beaten up.

Nadia also met human rights lawyer Amal Clooney, who will represent her and various other women who were tortured by the Isis. Their case is being taken to the International Criminal Court.

Nadia's website says that Iraqi woman "dedicated to helping women and children victimised by genocide, mass atrocities and human trafficking, heal and re-build their lives and communities."
