Thousands of people gathered north of Paris on Saturday to support Iranian opposition protesters and an Iranian exile group pushing to be rid of a terrorist label.
Crowds spilled out of buses and filled the fairground in Villepinte under drizzly skies. Organizers said 1,000 buses were hired to bring protesters from around France and Europe, including legislators from several countries.
The rally was organized by the National Council of Resistance of Iran.
The France-based umbrella group includes the People's Mujahedeen Organization of Iran, which was recently removed from the European Union's list of banned terrorist groups. The group, also known as the Mujahedeen-e-Khalq is trying to persuade the US to stop classifying it as a terrorist group, as well.
The leader of the National Council, Maryam Rajavi, is expected to speak later Saturday.
