Coniston massacre
The Coniston massacre, which took place near the Coniston cattle station in the then Territory of Central Australia (now the Northern Territory) from 14 August to 18 October 1928, was the last known officially sanctioned massacre of Indigenous Australians and one of the last events of the Australian Frontier Wars. People of the Warlpiri, Anmatyerre, and Kaytetye groups were killed. The massacre occurred in revenge for the death of dingo hunter Frederick Brooks, killed by Aboriginal people in August 1928 at a place now known as "Yukurru", also known as Brooks Soak.
Celle massacre
The Celle massacre (euphemistically called ""Celler Hasenjagd"", "hare chase of Celle") was a massacre of concentration camp inmates that took place in Celle, Prussian Hanover, in the last weeks of the Second World War. On 8 April 1945 over 3,000 concentration camp internees were killed in an Allied air raid and subsequent attacks by SS guards, Gestapo, and Nazi party officials, as well as members of the public. Some of the perpetrators of the massacre were later tried but all of those convicted for the crime were set free in the early 1950s.
