Protesters chanted slogans against the detentions, accusing the French authorities of a “shameful deal with the mullahs”.
Tehran has been pressing the French authorities to take action against the group.
Demonstrators believe those being held include Maryam Rajavi, wife of the People’s Mujahideen leader, Massoud Rajavi.
Well over $3m in cash as well as computers and communications equipment were also seized in the raids.
I don’t think this group is one that we should shed tears for, necessarily, but it seems pretty likely that the French are doing this largely to suck up to the mullahs.
