United Nations agencies have begun an assessment mission in northwestern Uganda following the mass displacement of Sudanese refugees by Ugandan rebels, an official of the UN High Commissioner for Refugees (UNHCR) told IRIN on Monday. The UNHCR spokesman for Uganda, Dennis Duncan, said an assessment team comprising UNHCR, World Food Programme and UN Development Programme officials had been sent to the affected districts of Moyo and Adjumani "to figure out where it is safe and where it is not".
