The Church Street bombing was a car bomb attack on 20 May 1983 in the South African capital Pretoria by Umkhonto we Sizwe, the military wing of the African National Congress. The bombing killed 19, including two perpetrators, and wounded 217, and was one of the most deadly attacks engaged in by the ANC during its armed struggle.
The attack consisted of a car bomb set off outside the Nedbank Square Building, which was shared between Nedbank and the Dutch embassy, on Church Street at 4:30 pm on a Friday. The target was South African Air Force (SAAF) headquarters, but as the bomb was set to go off at the height of rush hour, those killed and wounded included civilians. The bomb went off ten minutes earlier than planned, killing two of the perpetrators, Freddie Shangwe and Ezekial Maseko. At least 20 ambulances took the dead and wounded to hospitals.
In submissions to the Truth and Reconciliation Commission (TRC) in 1997 and 1998, the ANC revealed that the attack was orchestrated by a special operations unit of the ANC's Umkhonto we Sizwe (MK), commanded by Aboobaker Ismail. At the time of the attack, they reported to Joe Slovo as chief of staff, and the Church Street attack was authorised by Oliver Tambo.
The ANC's submission said the bombing was in response to a South African cross-border raid into Lesotho in December 1982, which killed 42 ANC supporters and civilians, and the assassination of Ruth First, an ANC activist and the wife of Joe Slovo, in Maputo, Mozambique. It claimed that 11 of the casualties were SAAF personnel and hence a military target. The legal representative of some of the victims argued that as administrative staff including telephonists and typists they could not accept that they were a legitimate military target.
