The US and UN imposed sanctions and an arms embargo on the Sudanese government following accusations of genocide and ethnic cleansing in Darfur. Neither of these have worked, and as the International Criminal Court issued arrest warrants for members of government and militant groups, the Sudanese Government denied the ICC had jurisdiction over the matter and expelled 13 aid organisers in a backlash. This has only caused the conditions in refugee camps to worsen and harmed the peace process.
As UN sponsored refugee camps across Africa fall into a states of chaos, the UN needs to rethink its handling of war zones and refugee camps. In refugee camps in countries such as Sudan, Liberia and the Democratic Republic of Congo malaria and HIV are reaching epidemic proportions, sanitation is sometimes non-existent and UN peacekeepers are being accused of a wide array of sex crimes. These are all indicators of a systematic failure of the UN's feet-on-the-ground policy in these regions and is in drastic need of reform.
