between Egypt and Sudan have a strip of land called the Bir Tawil. None of these countries do not recognize it its territory. Bir Tawil covers an area of 2060 square kilometers and has the shape of a quadrangle.
Neutral territory arose from a misunderstanding. In 1899 the territory of North Africa, the United Kingdom controlled. She established the border between Egypt and Sudan on the 22 th parallel. However, in 1902, Britain launched a new "administrative border", regardless of "political borders" and the triangle of land above the 22th parallel was under the control of the Sudan.
Egypt argues that the real border - the one that was installed in 1899. Sudan adheres to the boundary 1902. Thus, Bir Tawil did not actually belong to any one country, because international law they had no grounds to claim the land. For any third country, never took part in the debate, to demand land itself is also possible. Thus, Bir Tawil is one of a few unclaimed by any land masses on the Earth. Resident population in this place is not.
