The protesters waved Iranian flags and banners in violet, as well as portraits of Maryam Rajavi, the president-elect of the National Council of Resistance of Iran (NCRI), whose main component is the People's Mojahedin Organization of Iran (PMOI). In a message read by a participant, Maryam Rajavi urged the international community "to establish a special tribunal under UN auspices, in order not to leave unpunished those responsible for the massacre of 1988, one of the biggest political crimes since the Second World War.
The former bishop of Evreux, Bishop Jacques Gaillot, also claimed that "justice is done," speaking in front of pictures of dozens of victims of executions.
From August 1988 to February 1989, Iranian authorities conducted mass executions of political prisoners. Nearly 5,000 prisoners were killed, according to Amnesty International. The NCRI evokes the figure of 30,000 deaths.
