NEW YORK -- Nicole Kidman says that after seeing women and children who were victims of violence in Kosovo 10 years ago, she decided that one of the most important things in her life was to work to help them.

The Academy Award-winning actress told a fundraising dinner Wednesday night marking the 20th anniversary of the UN Trust Fund to End Violence against Women, that she has been speaking out ever since "to be a voice for the women who don't have a voice."

Kidman, who is a goodwill ambassador for UN Women, urged the guests "to undo your wallets," saying these women and girls "need us who have the ability, who have the money," to help them.

UN Women said the dinner raised over $105,000, including a $50,000 donation from Kidman.
