More violence hits Tunisian streets
Violent protests have erupted on Tunisia's streets again as the country struggles to deal with the aftermath of overthrowing its president.
Police fired tear gas and rioters smashed police cars as tensions resumed in the capital Tunis.
Scores of protesters from Tunisian provinces gathered in front of the prime minister's office, shouting anti-government slogans and breaking the windows of nearby cars.
The crowd included people who had defied a nationwide curfew and staged a sleep-in overnight.
Schools were due to reopen on Monday after being closed during the unrest, but teachers went on strike.
The protesters are angry that remnants from former president Zine El Abidine Ben Ali's regime hold leading posts in the interim government in place since last week.
Ben Ali fled the country on January 14 after 23 years in power, pushed out by weeks of deadly protests driven by anger over joblessness, corruption and repression.
Noisy street demonstrations have continued since his departure, but most have been peaceful.
State TV also reported that a former Ben Ali political adviser who had been sought by police, Abdelwaheb Abdallah, had been found and placed under house arrest.
Police have cracked down on key allies of the former president, placing two high-ranking officials under house arrest and detaining the head of a popular private TV station for allegedly trying to slow down the country's steps toward democracy.
