The Sharpeville massacre occurred on 21 March 1960 at the police station in the township of Sharpeville in the then Transvaal Province of the then Union of South Africa (today part of Gauteng). After demonstrating against pass laws, a crowd of about 7,000 protesters went to the police station. Sources disagree as to the behaviour of the crowd: some state that the crowd was peaceful, while others state that the crowd had been hurling stones at the police and that the mood had turned "ugly". The South African Police (SAP) opened fire on the crowd when the crowd started advancing toward the fence around the police station; tear-gas had proved ineffectual. There were 249 victims in total, including 29 children, with 69 people killed and 180 injured. Some were shot in the back as they fled.
