Khartoum (state)
Khartoum State () is one of the eighteen states of Sudan. Although it is the smallest state by area (22,142 km), it is the most populous (5,274,321 in 2008 census). It contains the country's second largest city by population, Omdurman, and the city of Khartoum, which is the capital of the state as well as the national capital of Sudan. The capital city contains offices of the state, governmental and non-governmental organizations, cultural institutions, and the main airport.
Juba
In 2005, Juba became the interim seat and the capital of the Autonomous Government of Southern Sudan, although the proposed interim capital before the signing of the Comprehensive Peace Agreement was Rumbek. With the advent of peace, the United Nations increased its presence in Juba, whereas many Southern Sudan operations had until that time been managed from Kenya. Under the leadership of the United Nations Office for the Coordination of Humanitarian Affairs, the United Nations established a camp known as "OCHA Camp", which served as a base for many United Nations agencies and non-governmental organizations.
