evidence: Ankoko Island (Spanish: Isla de Anacoco) is an island located at the confluence of the Cuyuni River and Wenamu River, at 6°43′N 61°8′W, on the border between Venezuela and Guyana. The status of the island is subject to the Geneva Agreement, which was signed by the United Kingdom, Venezuela and British Guiana on 17 February 1966. This treaty stipulates that the parties will agree to find a practical, peaceful and satisfactory solution to the border dispute.[1] Venezuela, which claims Ankoko Island as its own in the Guyana–Venezuela territorial dispute, established a military base on the island in 1966, which Guyana claims as an intrusion and aggression on its sovereign territory. [...] Subsequently, on the morning of the 14 October 1966, Forbes Burnham, as Prime Minister and Minister of External Affairs of Guyana, dispatched a protest to the Foreign Minister of Venezuela, Ignacio Iribarren Borges , demanding the immediate withdrawal of Venezuelan troops and the removal of installations they had established.[6] Venezuelan minister Ignacio Iribarren Borges replied stating "the Government of Venezuela rejects the aforementioned protest, because Anacoco Island is Venezuelan territory in its entirety and the Republic of Venezuela has always been in possession of it".[6] The island remains under Venezuelan administration, where a Venezuelan airport and a military base operate.[6]
