The Church Street bombing was a car bomb attack on 20 May 1983 in the South African capital Pretoria by Umkhonto we Sizwe, an activist group co-founded by Nelson Mandela, Joe Slovo and Walter Sisulu which served as the military wing of the African National Congress. The bombing killed 19 and wounded 217,[2] and was one of the largest attacks engaged in by the ANC during its armed struggle against apartheid.
