26.02.2011 - Thousands of Tunisian demonstrators gather near the prime minister's office in Tunis, 25 February 2011 Mass protests forced out veteran President Zine al-Abidine Ben Ali last month
Security forces in the Tunisian capital have fired tear gas to try to disperse hundreds of demonstrators outside the interior ministry.
Police and masked men in civilian clothes, armed with sticks, moved through streets looking for protesters.
The renewed protest comes a day after police cleared huge crowds from the streets demanding the resignation of the interim prime minister.
That was the biggest rally since the president fled after weeks of unrest.
On Friday police fired tear gas and warning shots to disperse demonstrators.
