Tunisian police have fired shots into the air outside the headquarters of the RCD party.
They were trying to disperse hundreds of protesters who surrounded the building, demanding that ministers associated with the regime of the ousted President Ben Ali leave the government for good.
There were angry scenes but eventually the troops were won round. Later, workmen removed the party sign from outside the building. Its fall was met with rapturous cheers.
Veteran opposition figure Najib Shebbi told euronews that reacting to calls from the street is not always the best way forward. Dissolving the RCD party is not an obligation, he said, but separating it from the apparatus of state is.
The prime minister and caretaker president left the RCD earlier this week. Ministers in the interim cabinet resigned from the party to boost its credibility. Another minister left the government today, bringing the total this week to five.
