Halaib Triangle
The Halaib Triangle is an area of land measuring 20,580 square kilometres (7,950 mi2) located on the Northeast African coast of the Red Sea. The area, which takes its name from the town of Halaib, is created by the difference in the Egypt–Sudan border between the "political boundary" set in 1899 by the Anglo-Egyptian Condominium, which runs along the 22nd parallel north, and the "administrative boundary" set by the British in 1902, which gave administrative responsibility for an area of land north of the line to Sudan, which was an Anglo-Egyptian client at the time.
