Hundreds of protesters in Tunisia have gathered outside the prime minister's office in Tunis in defiance of an overnight curfew.
They are demanding the resignation of the interim government, which is dominated by allies of ousted president Zine al-Abidine Ben Ali.
Mr Ben Ali was overthrown earlier in January in a popular uprising over poverty, corruption and political repression.
It is the first time since the curfew was imposed that the demonstrators have ignored it, the BBC reports.
The demonstrators say they will stay on the streets until all ministers who served the former regime, including Prime Minister Mohamed Ghannouchi, have resigned.
They say they can not trust such politicians to deliver the democratic reforms they want. Many have come from the south where the uprising began in December.
There have been daily protests in Tunis and other cities against the interim government which contains many loyalists from Mr Ben Ali's era, including Mr Ghannouchi.
Mr Ghannouchi has pledged to quit after elections, which are expected within six months, but protesters want him to resign immediately, the BBC reports.
To show that it is willing to deal with the wrongs of the past, the interim government has put advisers of the outsted president under house arrest and detained the owner of a private television channel close to the family of Mr Ben Ali.
Former presidential adviser Abdelaziz bin Dhia and former Interior Minister Abdallah Qallal are under house arrest, state media is reporting.
The owner of a private TV station and his son have also been arrested for "grand treason" for inciting violence and working for Mr Ben Ali's return.
