New protests have broken out on the streets of Tunisia's capital, Tunis, hours before the expected announcement of a new national unity government.
Police used water cannon, teargas and occasional gunshots to disperse several hundred demonstrators calling for the party of ousted President Zine al-Abidine Ben Ali to relinquish power.
The country has been in a state of emergency since he fled on Friday.
PM Mohammed Ghannouchi says a deal between parties will be unveiled later.
Mr Ben Ali, who had been in power for 23 years, fled to Saudi Arabia on Friday after a month of mounting protests across the country over unemployment, food price rises and corruption.
