evidence: The Island of Vukovar (Serbo-Croatian: Vukovarska ada, Вуковарска ада, pronounced [ʋûkoʋaːrskaː ǎːda] or [-ǎda]) is a disputed island on the river Danube. It is situated close to the city of Vukovar, Croatia. During the existence of SFR Yugoslavia, the island was part of SR Croatia. In 1991. Croatia declared independence. It was the opinion of the Badinter Arbitration Committee that the borders between the republics should become the borders between the countries,[1] but it was under Serbian control like other parts of Eastern Slavonia, Baranja and Western Srem (east Croatia) at the time. In the Croatian War of Independence, the Yugoslav People's Army and Serbian paramilitary forces occupied the island. After the Erdut Agreement in 1998, Eastern Slavonia, Baranja and Western Srem were rejoined with Croatia, but the island of Vukovar was left under Serbian military occupation, as was the Šarengrad island.[2] [...] One part of the peace agreements has been the short-term deal that Croatia will control the western part and Serbia eastern part of the Danube.[6] The official Serbian position is that the Badinter Arbitration Committee opinion is invalid and that this short-term deal between Croatia and Serbia is to be the future border between the states thus Vukovar island is part of Serbia as it is closer to the Serbian shoreline.[7]
