German, Italian and Hungarian occupying forces engaged in atrocities against the Yugoslavian population, in the form of mass-killings of civilians and hostages in retaliation for Partisan attacks and resistance. Infamous examples include the Kragujevac massacre, committed by German forces, as did the Albanian "Waffen-SS" units, which murdered more than 400 Orthodox Christian civilians at Andrijevica, the Novi Sad raid, committed by Hungarian forces and crimes committed by Italian forces, such as in Podhum.
