Khartoum : With a population of 5,274,321, its metropolitan area is the largest in Sudan, the sixth-largest in Africa, and the fourth-largest in the Arab world. Khartoum is located at the confluence of the White Nile, flowing north from Lake Victoria, and the Blue Nile, flowing west from Ethiopia. The location where the two Niles meet is known as al-Mogran or al-Muqran (المقرن; English: "The Confluence"). From there, the Nile continues to flow north towards Egypt and the Mediterranean Sea.
Divided by these two parts of the Nile, Khartoum is a tripartite metropolis with an estimated overall population of over five million people, consisting of Khartoum proper, and linked by bridges to Khartoum North (الخرطوم بحري al-Kharṭūm Baḥrī) and Omdurman (أم درمان Umm Durmān) to the west.
