Before the protesters broke through a police barrier to rally in central Tunis, police warned them by loudspeaker that their demonstration was illegal, but that they would not stop them by force.
Up to one thousand protesters then pushed through the cordon to reach Habib Bourguiba Avenue, where most rallies take place.
The protest is being watched to see how far the National Salvation Front and its constituent parts can mobilise supporters in public after the arrests, and how much force the police are willing to use against them.
Former member of the Tunisian parliament, Saida Ounissi, said what makes the recent protests unique to other anti-government rallies that have taken place is the popularity of the movement.
In recent weeks, several of the Front’s top leaders have been arrested, as part of a crackdown on prominent critics of Saied, and charged with conspiring against state security.
