United Nations investigators have found 11 mass graves thought to contain the bodies of 68 villagers in Ivory Coast’s main city of Abidjan.
Last month UN teams found more than 200 bodies buried in a mass grave in the western town of Duekoue.
According to the local chief, Ibrahim Bakayoko, the victims in Abidjan belonged to a tribe loyal to President Alassane Ouattara.
“(Former president Laurent) Gbagbo was arrested Monday, and on Tuesday everybody was at home, children too. And then suddenly, just like that they started to break down doors… Even if you tried to go into your home, they followed you and killed you,” said Bakayoko.
The capture of Gbagbo in April by pro-Ouattara forces after four months of fighting was supposed to end the violence.
The unrest had been triggered by Gbagbo’s refusal to concede defeat in last November’s presidential election.
UN human rights officials announced last week that they were investigating reports of mass graves in several areas and the possible killing of civilians by both sides.
