The bulk of the territory in dispute is in the vicinity of the town of Apatin, while the Island of Šarengrad and the Island of Vukovar are cited as particularly contentious parts of the dispute.
On 28 July 2002, warning shots were fired by a patrol boat of the Yugoslav Army at four boats carrying the prefect of Vukovar-Srijem County and the mayors of Vukovar and Bačka Palanka, as well as several other civilians to Bačka Palanka.
