More than 200 protesters from around Tunisia descended on the capital Sunday to join demands to rid the interim government of holdovers from the ousted former president's regime.

The demonstrators rallied near the prime minister's office in Tunis, waving banners and photos of a young man who set himself on fire, triggering the popular uprising that overthrew President Zine El Abidine Ben Ali.

"Bouazizi gave his life for his country," read one banner honoring 26-year-old Mohamed Bouazizi, who committed suicide in the central city of Sidi Bouzid last month to protest official harassment under Ben Ali's regime.

The "Caravan of Freedom" left Saturday on a 320-kilometer (200-mile) trek to Tunis by car, truck and motorcycle from around Sidi Bouzid, said protester Tahri Nabil. Some protesters hitchhiked.

"We don't want Sidi Bouzid to continue to be marginalized like it was in the previous decades," said Nabil, a French language teacher who lives in the town of Menzel Bouzayane near Sidi Bouzid.
