On March 29, 1988, South African anti-apartheid activist Dulcie September was shot dead at close range in central Paris. In the 1970s, she had been imprisoned in her home country for her activities against the apartheid regime. Upon her release, she had been authorised to leave South Africa on the condition that she never return. September was the representative of Nelson Mandela’s ANC party in France and yet she claimed to be followed and watched. What did the French secret services know? FRANCE 24’s Caroline Dumay, Stefan Carstens and Nadine Theron revisit the case.
