Halaib Triangle, to the east, which is adjacent to the Red Sea, with the side effect that Bir Tawil is unclaimed by either country (each claims the other owns it). Bir Tawil has no settled population, but the land is used by Bedouins who roam the area. Gornja Siga and other pockets Croatia and Serbia dispute several small areas on the east bank of the Danube. However, some pockets on the west bank, of which Gornja Siga is the largest, are not claimed by either country. Croatia states the pockets are Serbian, while Serbia makes no claims on the land. On 13 April 2015, Vít Jedlička from the Czech Party of Free Citizens proclaimed the right-libertarian micronation of Liberland on Gornja Siga. The Croatian Ministry of Foreign and European Affairs has rejected these claims, stating that the differing border claims between Serbia and Croatia do not involve terra nullius, and are not subject to occupation by a third party. The Serbian Ministry of Foreign Affairs stated on 24 April 2015 that while Serbia considers "Liberland" to be a frivolous matter, it does not impinge upon the Serbian border, which is delineated by the Danube. Historical claims of terra nullius Several territories have been claimed to be terra nullius. In a minority of those claims, international and domestic courts have ruled on whether the territory is or was terra nullius or not. Africa Burkina Faso and Niger A narrow strip of land adjacent to two territorial markers along the Burkina Faso–Niger border was claimed by neither country until the International Court of Justice settled a more extensive territorial dispute in 2013. The former unclaimed territory was awarded to Niger. Western Sahara At the request of Morocco, the International Court of Justice in 1975 addressed whether Western Sahara was terra nullius at the time of Spanish colonization in 1885. The court found in its advisory opinion that Western Sahara was not terra nullius at that time. Asia Pinnacle Islands (Diaoyu Islands/Senkaku Islands) A disputed archipelago in the East China Sea, the uninhabited Pinnacle Islands, were claimed by Japan to have become part of its territory as terra nullius in January 1895, following the Japanese victory in the First Sino-Japanese War. However, this interpretation is not accepted by the People's Republic of China (PRC) and the Republic of China (Taiwan), both of whom claim sovereignty over the islands.
