This 39-page report is based on five research missions to the hard-to-access rebel-held areas in the two states and to refugee camps in South Sudan. It documents the government’s indiscriminate bombing and other attacks on civilians since conflict between the government of Sudan and the rebel Sudan People’s Liberation Army-North (SPLA-N) broke out in June 2011 in Southern Kordofan following disputed state elections. The report also describes the effect of Sudan’s refusal to allow humanitarian assistance into rebel-held areas. Hundreds of thousands of people are displaced inside the two states, surviving on very little, while more than 200,000 have fled to refugee camps in South Sudan and Ethiopia.
