CNDD-FDD won a sweeping victory in 2005 elections, organized in large part by the United Nations Operation in Burundi (Opération des Nations Unies au Burundi, ONUB), a peacekeeping mission. In late 2006, ONUB troops left the country and the UN mission transitioned into a predominantly civilian operation, the United Nations Integrated Office in Burundi (Bureau Integré des Nations unies au Burundi, BINUB). BINUB’s mandate includes the promotion of both democracy and human rights.[26] A political section works with the government and political parties on strengthening democratic institutions, while a human rights section, fused with a pre-existing mission of the Office of the High Commissioner for Human Rights (OHCHR) in Burundi, monitors rights abuses.[27] Another section is dedicated to security-sector reform.
