The United Nations says that the Democratic Republic of Congo is facing one of the world’s biggest displacement and humanitarian crises. Around 6.9 million people have fled their homes to escape violence caused by more than 250 rebel groups operating across the country. Emery Makumeno, a reporter in Kinshasa, explains the origins of the 30-year conflict and motivations of several rebel groups. And Byobe Malenga, a journalist with BBC Swahili, describes the difficult conditions he saw recently when visiting camps for displaced people in the Kivu region.
