Hala'ib Triangle is located on the Egyptian–Sudanese border and occupies 20,580 square kilometers. This territory on the 22nd parallel has substantial value because of extensive oil reserves concentrated in the area. Most of the Gabal Elba National Park is situated in the Hala'ib Triangle.
The conflict between Cairo and Khartoum erupted when Cairo transferred two islands to Riyad. Moreover, at the beginning of 2019, Egypt announced an international tender for the exploration and production of oil and gas in the areas of Halayeb and Shalateen. Then, the Foreign Ministry of Sudan handed a note of protest to the ambassador of Egypt in Khartoum.
Hala'ib is closely connected with another African territory, Bir Tawil. However, neither Egypt nor Sudan are interested in the area. This is an uninhabited territory with no fresh water. On the map, Bir Tawil has an inverted quadrilateral shape.
