On 29 March 1988, Dulcie September, the African National Congress (ANC) representative in France, Luxembourg and Switzerland was asassinated in Paris. She was shot five times in the back by an assassin just after collecting her mail and opening the ANC Paris office in 28, Rue des Petites-Ecuries. September was investigating a possible illicit weapons trade (including nuclear material) between France and the Apartheid government in South Africa.  Sergeant-Major Joseph Klue of the South African Defence Force (SADF) became a possible suspect and the French were accused of complicity in the incident. In the aftermath, former Secretary General of the ANC, Alfred Nzo commented: "if ever there was a soft target, Dulcie September was one."
