Jastrebarsko children's camp
The Jastrebarsko children's camp held Serb children who had been brought there from various areas of the Axis puppet state, the Independent State of Croatia (Croatian: Nezavisna Država Hrvatska, NDH), during World War II. The children had been captured as a result of massacres and counter-insurgency operations conducted by the genocidal Ustaše-led government, its Axis allies and other collaborators since the Axis invasion of Yugoslavia and establishment of the NDH in April 1941. The camp was located in the town of Jastrebarsko, about 37 kilometres (23 mi) southwest of the NDH capital, Zagreb, and operated from 12 July until October 1942.
