The protest came just days after Britain's decision to lift its ban on the People's Mojehedin Organisation of Iran (PMOI), a move Iran denounced as a "disgrace", AFP reported.
The European Union and the United States still have the PMOI listed as a terrorist organisation.
Delegations of Iranian PMOI supporters from Germany, Australia, Belgium, Canada, the United States, Britain, Iraq and Jordan took part in the assembly in a hall in the Villepinte suburb of Paris, according to organisers.
