3 February 1988
Fighting between Inkatha Freedom Party (IFP) and the United Democratic Front (UDF) supporters spilled into central Pietermaritzburg when the Congress of South African Trade Unions (Cosatu) offices in the town were attacked by a mob armed with pangas and other weapons. Cosatu and the UDF were seen to be challenging IFP's hegemony in KwaZulu-Natal; and their alleged links with the banned African National Congress (ANC) made them an obvious target of Inkatha and state covert forces.
