Rape as a Weapon of War

There was a wonderful article in the May 11 issue of the Christian Science Monitor exploring how rape has been used as a weapon of war in Colombia. Although this is nothing new to those of us familiar with the disproportionate amount of violence against women and girls, it's still refreshing to see it explicitly addressed in the media.

At the end of the article, there are links to articles addressing rape as a tactical weapon in the Congo and Iraq.

Does anyone know of any other good articles/books on this topic?
