evidence: Bir Tawil – which means "deep well" in Arabic – is a slice of land just south of the border between Egypt and Sudan that runs primarily in a straight line along the 22nd parallel. Its fate appears ensnared in that of the nearby Hala’ib Triangle, a larger, more strategic territory by the Red Sea contested by the two countries. In 1899, British rulers produced a map that gave Bir Tawil to then Anglo-Egyptian Sudan and the Hala’ib Triangle to Egypt. But in 1902, it produced another map with the opposite designations. [...] Egypt recognises the 1899 map, which gives it the more prised Hala’ib Triangle. Sudan uses the later map giving it the territory. Neither, therefore, appears to want Bir Tawil.
