Demonstrators have criticized the country's new unity government announced Monday for being mostly made up of old guard politicians from the ruling party. They are seeking the disbanding of the RCD party, founded by ousted President Zine El Abidine Ben Ali, who fled to Saudi Arabia on Friday after 23 years in power.
Outside the gates of the party headquarters in Tunis, the army fired about 10 rounds into the air, scattering some protesters in the noisy but peaceful crowd. Others remained, chanting, "Down with the RCD!"
The warning shots came after a period of relative calm in Tunisia, which has been rattled by more than a month of unrest over the lack of jobs and corruption in Ben Ali's regime. Police even let protesters break a curfew Thursday night to hold a sit-in near the Interior Ministry.
A caretaker government is now struggling to calm this moderate Muslim nation on the Mediterranean Sea, popular among European tourists and seen as an ally in the West's fight against terrorism.
Although the unity government includes a few opposition leaders for the first time, demonstrators say the big jobs are still in the hands of Ben Ali's cronies.
Members of the interim government who belonged to the longtime ruling party quit the party on Thursday, the official TAP news agency said Thursday. Prime Minister Mohamed Ghannouchi and interim President Fouad Mebazaa had already quit the RCD earlier in the week.
In another attempt to ease tensions, the interim government has released all the country's political prisoners.
National television also reported that least 33 members of Ben Ali's family were taken into custody as they tried to flee the country, and national prosecutors are investigating overseas bank accounts, real estate and other assets held by Ben Ali, his wife Leila Trabelsi and other relatives.
Swiss officials froze all assets tied to Ben Ali's family on Wednesday, estimating that Tunisian officials have put about $620 million into Swiss banks. In Paris, anti-corruption group Transparency International France and two other associations filed suit alleging corruption by Ben Ali and his wife.
A French government minister said the Tunisian central bank director, Taoufik Baccar, has resigned following widespread rumors that the president's wife fled the country with a huge stash of gold.
Tunisia's Central Bank took control of Banque Zitouna, a bank founded by a son-in-law of Ben Ali, to protect its deposits.
