Tunis: Four people have died in a fresh unrest in the Tunisian capital after a clash between stone-throwing protesters and police. The protestors were demonstrating against the interim government.

In a statement, the Interior Ministry has blamed ‘provocateurs’ for fomenting violence in peaceful rallies.

The ministry said already three people have died, and more than 200 people have been arrested in last two days.

Demonstrators fear the interim government has hijacked the revolution that drove Tunisia's longtime autocrat from power on January 14, sending shock waves through the Arab world.

On Saturday, police and troops backed by tanks used tear gas to disperse hundreds of youths protesting against the caretaker government.

Officers were seen chasing some youths through town after the rally ended.

Authorities then ordered a temporarily ban on vehicle and pedestrian traffic on the capital's central Bourguiba Avenue till Sunday.
