The 1902 border assigned administration of the territory of the Ababda tribe south of the 22-degree latitude line to Egypt, and gave to Sudan the grazing land of the Beja tribe north of the line to administer. The Sudan-administered territory comprised about 18,000 km2, including the towns of Halaib and Abu Ramad. When Sudan became independent in 1956, Egypt regarded the latitude 22° territorial boundary of 1899 as the border between the two countries, while Sudan held to the claimed 1902 administrative boundary. As a result, both Egypt and Sudan claim sovereignty over the territory. Conversely, the area south of the line which had been administered by Egypt, Bir Tawil, is a "terra nullius", claimed by neither country.
