Yazidi activist Nadia Murad, a survivor of IS sex slavery, implored the global community to help free hundreds of women and girls still held by the jihadists in her Nobel acceptance speech Monday, saying the world must protect her people.

"If we want the Yazidis to leave displacement camps and return to their areas, and give them confidence again, the international community should provide them with international protection under United Nations supervision," she said at the ceremony in Oslo.
