The Petrinja Killings refers to a series of mass murders and other crimes that were committed by various Serb forces against Croat POWs and civilians, from September 1991 until June 1992, in the town of Petrinja and in surrounding areas. Croats were killed over several months, both during the battle to control the town and later during the occupation; in indiscriminate artillery attacks against civilian areas and in instances of wilful killings against civilians and POWs. Croatian sources state that over 250 people were killed (including 120 civilians) during these crimes.
