With our special correspondent in Pretoria, Claire Bargelès

For filmmaker Enver Samuel, it is important that his film continues to circulate, to support the request to reopen the file with French justice:

"It is not simply a matter of knowing who pulled the trigger, but also who decided on this assassination. The family wants to have all these answers, and to know why there was all this long silence. I think that today, we must try to make enough noise for the case to be reopened."

The documentary follows the investigation of journalist Evelyn Groenink and the supposed links between the assassination of Dulcie September and her research into French weapons sales to the apartheid regime under embargo.

It may therefore be surprising that the screening takes place within the residence of France, but for ambassador Aurélien Lechevallier, light must be shed on this case:

"There are indeed suspicions that concern the involvement of certain services, not only French but also South African. I believe that we must be comfortable with all of this, it is part of a work of memory. As you have seen, on the African continent and elsewhere, France is engaged in this work of memory. We must be transparent, we must be clear and we must participate in this work with everyone, so that the truth is established and if possible all justice is rendered."

According to Enver Samuel, the request to reopen the file should be examined again by French justice in the coming weeks.
