Khartoum is the capital of Sudan and is located where the Blue and White Niles merge to form the Nile. The huge, spread-out city is actually made out of three distinct cities - Khartoum, Khartoum North or Bahri, and Omdurman - which are divided by the Nile and its two arms. The Blue Nile flows between Khartoum and Bahri, the White Nile between Khartoum and Omdurman, and the merged Nile between Bahri and Omdurman. The confluence of the Blue and White Nile, known as Al-Mogran, lies just north of the bridge between Khartoum and Omdurman.
