The U.N. Development Fund for Women has launched a new advocacy campaign to end violence against women. The fund has recruited Hollywood actress Nicole Kidman to help promote the campaign, which is an internet-based initiative that asks people to sign a "virtual book" that promotes women's rights. The U.N. Fund says violence against women is the most pervasive human rights violation around the world. Women are subjected to domestic violence, trafficked across borders, and the victims of systematic rape in conflict zones. The United Nations estimates that one in three women will be a victim of violence in her lifetime. The Development Fund for Women seeks to bring global attention to the issue and promote gender equality.
