Cite your motherfucking sources. 8,000... Shiiiittt, boy.

Stara Gradiška was the fifth subcamp of the Jasenovac concentration camp, established in 1941 to the east of the main camp near the village of Stara Gradiška. The camp was specially constructed for women and children of Jews, Gypsies, Serbs, and guerrillas.

Eventually more than 50,000 men, women and children were incarcerated by the Ustaše in the medium camp and guarded by Germans and a few female Ustaše troops. All of the women guards were sisters or wives of the male guards and they were known throughout the camp for their cruelty. Nada Tanić Luburić, sister of the first commandant of Jasenovac Maks Luburić, and wife of the second was personally pointed out as one of the diabolical female Ustaše guards in Stara Gradiška. It is estimated that she strangled more than 8,000 women with another female guard.
