The humanitarian crisis in the eastern part of the Democratic Republic of the Congo (DRC, DR Congo) continues to deteriorate amid ongoing conflict that has displaced tens of thousands of people and caused widespread hunger, the United Nations World Food Programme (WFP) said on Friday. UN aid agencies are struggling in particular in provinces overrun by Rwanda-backed rebels from the March 23 Movement (M23). However, dramatic funding shortfalls for humanitarian operations have also contributed to the dire situation.
