More than 200 people have been arrested and dozens of police hurt during clashes in Tunisia, the interior ministry said on Wednesday, as anger over austerity measures spilt over into unrest.
The North African country has been hailed for its relatively smooth democratic transition since a 2011 revolt that sparked the Arab Spring uprisings, but seven years after the revolution, tensions over economic grievances are high.
Tunisia has seen rising anger over hikes in value-added tax and social contributions after a tough new budget was applied at the start of the year.
Interior ministry spokesman Khalifa Chibani told local radio that 49 police officers were wounded during a second night of clashes across the country Tuesday to Wednesday and that 206 "troublemakers" were arrested.
Properties were damaged, he said, including a branch of the Carrefour supermarket chain in a suburb of Tunis that was looted.
After a calm day on Wednesday, residents said demonstrators in the evening took to the streets of Tebourba, a town west of the capital Tunis where a man in his 40s died in unrest Monday night.
On a visit to a nearby town, Prime Minister Youssef Chahed condemned acts of "vandalism" that "serve the interests of corrupt networks to weaken the state", pointing the finger at a leftist party that called for protests.
Fresh clashes broke out Wednesday night in the northern town of Siliana, where youths threw stones and molotov cocktails at security forces. Police responded with tear gas, an AFP correspondent said.
There were similar scenes in Kasserine, a town in Tunisia's neglected central region, with protesters burning tires to block roads and some throwing stones at police.
The army has been deployed around banks, post offices and other government buildings in the country's main cities, the defence ministry said.
There have been no figures given for the number of protesters injured in the clashes.
On Tuesday night, hundreds of young people took to the streets of Tebourba for the funeral of the man who died.
Police have insisted they did not kill him. Health Minister Imed Hammami said that results of an autopsy would be made public on Thursday.
Unrest was also reported in the working-class neighbourhoods of Djebel Lahmer and Zahrouni on the outskirts of Tunis, the central cities of Gafsa and Kasserine, and the northern town of Jedaida.
In the central town of Sidi Bouzid, the cradle of the protests that sparked the 2011 uprisings, youths blocked roads and hurled stones, and the police retaliated with tear gas, an AFP reporter said.
A representative of Tunisia's Jewish community said two Molotov cocktails were thrown at the entrance to two Talmudic schools on the Mediterranean island of Djerba, but their interiors were not damaged.
