Angelina Jolie, Hollywood actress and special envoy to the United Nations High Commission for Refugees, attended a panel discussion at the African Union Summit in Johannesburg on Friday to discuss sexual violence against women across the globe."Think what it would mean if the 54 nations of the African Union press as one towards full rights and opportunities for women, not just for this great continent, but for the world," Jolie said.Jolie also said the problem is not just African. Rather, it is global. She added that there has been much more awareness regarding the issue, but progress is slow.
