Wangu Kanja of Kenya was raped in 2002 as she walked home from work in Nairobi. It was an act of ordinary thugs, not soldiers. But she started a group for victims that has ended up ministering to the many women were assaulted as a result of the political unrest of 2008.
Women and children are routinely the victims of tribal warfare, said Ms. Kanja. While the men are out fighting, they are not home to protect their families. For the rapists, she said, "It's a win situation. For them it's a victory."
Countries where it happens most
Going back to the earliest human record, invading armies have made sexual prey of the women and children in the lands of their conquest.
But in recent years these assaults have increased as military organizations condone and even encourage attacks as an effective tool of war.
Here are some of the global conflict zones where rape is or has been widespread, as reported in a brief completed in September 2010 for the Bonn International Centre for Conversion, an international agency focused on peace and development.
Democratic Republic of the Congo: Rape has been used as a military strategy, particularly by the Forces Democratique de liberation du Rwanda in retaliation against the DRC government. The victims are often told they are being punished for collaboration. Rapes are deliberately committed in front of witnesses, often family members, and gang rapes are common. Last year there were nearly 15,000 new cases of sexual assault reported in the DRC.
Sudan: Rape has been a constant tool the Janjaweed, an Arab militia that has been in conflict with Darfur rebel groups since 2003. Women are continually under threat and gang rapes are frequent. Some experts suggest it is a form of ethnic cleansing. Women who report the crime are often punished themselves.
Nepal: The armed conflict that raged between the Communist Party of Nepal and pro-government forces between 1996 and 2006 produced many rape victims, most of them young girls. The majority of the assaults appear to have been committed by government security services who acted with impunity.
Bosnia and Herzegovina: The Bosnia Serb militia is widely reported to have committed rapes during the civil war of the 1990s. There were rape camps where girls and women were brought to be sexually assaulted. Women were taken as sexual slaves. Fathers were forced to rape daughters and brothers to rape sisters.
East Timor: During the Indonesian occupation of East Timor between 1975 and 1999, there were reports of rapes committed both by the Indonesian military forces and by the Timorese militias. Women were taken as sex slaves, especially if they were known to be supportive of independence or married to a member of a pro-independence group.
How to stop it
There have been three resolutions of the UN Security Council since 2000 that call on parties in a conflict to protect women from sexual violence and urge countries to bring perpetrators to justice.
But Jody Williams says there has been no consistent enforcement.
"We have all these resolutions at the UN. They are fine. But if you don't try to get states to actively implement them, they are just words on paper," said Ms. Williams.
The Nobel Women's Initiative, of which Ms. Williams is a member, sees the solution in prosecution.
It argues that
-Impunity must be ended for sexual violence
-Money must be provided for medical and legal services
-A survivor-centric approach must be adopted for all programming
-The UN Security Council resolutions that aim to protect women and children from sexual assaults in conflict zones must be enforced
-There must be reparations for survivors
-Reporting of sexual violence must be standardized
-Prevention must be enhanced
Bev Oda, Canada's International Development Minister, said she raises the issue with foreign governments at every opportunity - especially in situations where the countries are receiving Canadian aid.
On a tour of Sri Lanka, Ms. Oda said she was invited to visit a police station at a refugee camp where rape victims could report the crimes. And it quickly became apparent that the police did not speak the same language as the women who had been assaulted.
"When I pointed it out to the President of Sri Lanka, he happened to have the chief of police in the same building so he brought him in and told him it was not acceptable," said Ms. Oda.
But "here were these victims who are living in tents and getting [no more than the]the necessities of life, not knowing what their futures are, being told that there is access to redress," she said. "However, when they go there [to the police station] there's no one there who can appropriately help them."
