In page Sijekovac killings:

"

The Croats retaliated by attacking the village of Sijekovac on the right side of the Sava River, across from Croatia. At the time, as the Bosnian War was starting, it was still populated by members of all three ethnic groups of Bosnia and Herzegovina. After the initial reports in 1992, three members of the Presidency of Bosnia and Herzegovina arrived by helicopter to investigate a reported "dozen killed civilians".[3] The initial reported number of victims was eleven.[4]
