Scores of people took to the streets of Ivory Coast's main city, Abidjan, following the discovery of the body of an opposition supporter.
The latest demonstrations began in Abidjan's impoverished Adjame market district with protesters smashing car windows and marching in the streets.
Demonstrators set a number of vehicles on fire and blocked streets before truckloads of police showed up and fired tear gas on the demonstrators.
Unlike the violent demonstrations that have rocked Abidjan during the past week, this one was led by government opponents.
In the pro-government demonstrations, police did little to stop rampaging and looting. But for this one, security forces stepped in quickly to restore order.
The demonstrators, many of them Dioula-speaking people from Ivory Coast's north, turned out in the streets following the discovery of the body of a well-known television celebrity and supporter of opposition leader Alassane Ouattara.
Mr. Ouattara is from Ivory Coast's rebel-held north, where people have long accused the southern-based government of discriminating against them.
The body of Camara Yerefe, a television comedian, was found riddled with bullets at an expressway intersection. Witnesses in the Adjame district, where the celebrity lived, said he had been led away by security forces late Saturday.
Watching from nearby as Mr. Yerebe's body was removed was one northerner who asked not to be identified. He said as soon as he and others tried to set up barricades in the streets heavily armed police showed up and fired tear gas.
The demonstrator said as a northerner and a member of the opposition he is not allowed to demonstrate. If we try, he saod, the government forces will finish us. Those who support the government can demonstrate as much as they want, he said, because the country, for now, belongs to them.
Tens-of-thousands of government supporters marched Saturday in Abidjan, calling on President Laurent Gbagbo to back out of a French-brokered peace accord that he publicly accepted last week to end a four-month rebellion in the country.
The deal calls for the integration of rebels, most of whom are northerners, into the government.
A senior aide to President Gbagbo, Toussaint Alain, has called for the agreement to be renegotiated.
The deal was meant to end a four-month rebellion that has left about half the country under rebel control.
