Tunisia marked its final day of a three-day mourning period for those killed in the weeks-long massive public protests on Sunday, while new demonstrations were held to demand the resignation of the interim government, dpa reported.
French radio reported that about 1,000 people from the region of the city of Sidi Bouzid, where the protest movement had started in mid-December, marched in Tunis on Sunday.
The mainly youthful demonstrators chanted "the people want to topple the government," and demanded "clean" government - meaning one without any officials of the ousted regime of former president Zine el Abidine Ben Ali - the radio said.
The reports also said that hundreds of people from throughout Tunisia were heading towards Tunis on foot in a "caravan of liberation" and were expected to reach the capital in a few days' time.
Meanwhile trade unions were urging teachers to go on strike, a call coming as schools and universities were set to reopen in the new week.
The ongoing demonstrations come despite moves by the interim government to ease conditions in the wake of the "Jasmine Revolution" which toppled Ben Ali from power.
Among others, censorship was lifted, permitting foreign books, publications and films into the country without prior permission.
But with interim Prime Minister Mohammed Ghannouchi, interim President Foued Mebazaa and other ministers in the transition administration all having been allied with Ben Ali, Tunisian protests were expected to continue.
In a related development, in Switzerland the Zurich newspaper Neue Zuricher Zeitung (NZZ) reported Sunday that the first evidence of assets belonging to Ben Ali and his family clan had turned up, in accounts held in some top-name banks.
NZZ, reporting on the move by the Swiss government last week to freeze accounts belonging to Ben Ali and Ivorian President Laurent Ggabo, did not indicate the size or type of assets located.
But it cited a government message as saying that "it has turned out that assets of Zine Ben Ali and his family are deposited with the HSBC Private Bank, Citbank and Credit Suisse in Geneva."
While protests were continuing in Tunisia, attention was also being turned to neighbouring Algeria, where demonstrations took place in Algiers on Saturday, leading to numerous arrests and police attacking protesters with clubs and teargas.
The Algerian opposition RCD (Association for Culture and Democracy) had called the protests, where according to reports there were more than 40 people injured in clashes with police.
Demonstrations have been banned in Algeria since the imposition of a state of emergency in 1992.
