Input: Question: How many nations comprise the organization that Albania complained to concerning Royal Navy conducting mine-clearing operations in Albanian territorial waters, Passage:The Corfu Channel Incident refers to three separate incidents involving Royal Navy ships in the Straits of Corfu which took place in 1946, and it is considered an early episode of the Cold War. During the first incident, Royal Navy ships came under fire from Albanian fortifications. The second incident involved Royal Navy ships striking mines and the third incident occurred when the Royal Navy conducted mine-clearing operations in the Corfu Channel, but in Albanian territorial waters, and Albania complained about them to the United Nations. This series of incidents led to the Corfu Channel Case, where the United Kingdom brought a case against the People's Republic of Albania to the International Court of Justice. Because of the incidents, Britain, in 1946, broke off talks with Albania aimed at establishing diplomatic relations between the two countries. Diplomatic relations were only restored in 1991.
