In March 2004, Darfur, western Sudan, was described by the then United Nations (UN) Humanitarian Coordinator in Sudan, Mukesh Kapila, as "the world's greatest humanitarian crisis". Humanitarian organisations operating in Darfur are warning about malnutrition and famine in the region. Today's "worst humanitarian crisis" has been directly caused by war crimes and crimes against humanity for which the Sudanese government is responsible. The testimony of the Sudanese woman given above echoes hundreds of others, collected by Amnesty International, other human rights organisations, UN fact-finding missions and independent journalists. They all describe a pattern of systematic and unlawful attacks on civilians in North, West and South Darfur states, by a government-sponsored militia mostly referred to as "Janjawid"(armed men on horses) or "Arab militia" and by the government army, including through bombardments of civilian villages by the Sudanese Air Force. In these attacks, men are killed, women are raped and villagers are forcibly displaced from their homes which are burnt; their crops and cattle, their main means of subsistence, are burnt or looted. These massive attacks are the response of the Sudanese government to the insurgency of two armed political groups. These armed groups, mainly of Fur, Masalit and Zaghawa ethnicity were founded in 2003.
