In their attempts to suppress the resistance, German and Italian Fascist forces (especially the SS, Gestapo, and paramilitary militias such as Xª MAS and Black Brigades) committed war crimes, including summary executions and systematic reprisals against civilian population. Resistance captives and suspects were often tortured and raped. Some of the most notorious mass atrocities included the Ardeatine massacre (335 Jewish civilians and political prisoners executed without a trial in a reprisal operation after a resistance bomb attack in Rome), the Sant'Anna di Stazzema massacre (about 560 random villagers brutally killed in an anti-partisan operation in the central mountains), the Marzabotto massacre (about 770 civilians killed in similar circumstances) and the Salussola massacre (20 partisans murdered after being tortured, as a reprisal). In all, an estimated 15,000 Italian civilians were deliberately killed, including many women and children.
