In Ruvungi, a small village in the eastern Democratic Republic of Congo, a young disabled girl tells of being beaten and sexually assaulted by a policeman. If he tried to do it again, she says, she would kill him.

She is one of hundreds of women who have been assaulted or raped in Ruvungi, many of them during an attack by rebels in 2010 that lasted over several days. Some of them have found refuge at a women's shelter in town run by the charity Heal Africa, but the effects remain: children born from rape and angry husbands struggling to deal with the crime.

Much of the rape is tied to competition for extremely lucrative mineral resources, such as gold and tin mines. The perpetrators are rarely brought to justice, despite a United Nations presence.
