ABIDJAN (AFP) - More than 1,000 people were killed in western Ivory Coast during the five-month crisis that followed a disputed presidential election, the UN mission in the country announced Thursday. "At least 1,012 people, among them 103 women and 42 children, were killed" in political clashes and communal fighting, Guillaume N'gefa, the head of the mission's human rights division, told a press conference. Of the total, "at least 505 people were killed" in the town of Duekoue between December and the end of April, N'gefa said. The International Committee of the Red Cross (ICRC) has estimated that "at least 800 people" were killed on March 29 during communal violence in Duekoue, a stronghold loyal to former president Laurent Gbagbo. The west African country was wracked by violence after Gbagbo, who was in power for 10 years, refused to acknowledge in November 2010 that he had lost a presidential election to one-time prime minister Alassane Ouattara. Fighting broke out in districts of Abidjan, the commercial capital, and in the volatile west of the west African country, where militia forces and former rebels are active. The self-styled Republican Forces loyal to Ouattara, who was invested as head of state on May 21, overran Duekoue on March 29, on the eve of an offensive launched from the west, which led to Gbagbo's downfall. Gbagbo was captured in an underground bunker in Abidjan on April 11 by forces loyal to Ouattara, backed by France and the United Nations. The Ivorian authorities have given a toll for the post-electoral period of about 3,000 people killed. According to a report released Wednesday by Amnesty International, deadly reprisals are still being committed against Gbagbo's backers, six weeks after Ouattara gained power with the promise of reconciliation. "Human rights violations are still being committed against real or perceived supporters of Laurent Gbagbo both in Abidjan and in the west of the country," said Gaetan Mootoo, Amnesty International's west Africa researcher. "Alassane Ouattara's failure to condemn these acts could be seen as a green light by many of his security forces and other armed elements fighting with them to continue," he argued. "Alassane Ouattara must publicly state that all violence against the civilian population must stop immediately," demanded Mootoo. Ouattara has vowed to leave no crime unpunished and he has called on the International Criminal Court to launch an investigation, notably into crimes reported in the west. Amnesty's report criticised the UN mission in Ivory Coast for "inaction" and a failure to intervene at Duekoue, when UN troops were "based only a kilometre (half a mile) from the main centre of the killings" in the region. "I'm surprised by this declaration," UN special envoy for west Africa Said Djinnit said Thursday in Dakar, adding that the UN mission in Ivory Coast "deployed all its forces to ensure the protection of citizens." An international commission of inquiry from the UN Council for Human Rights is currently in Ivory Coast and is expected to make its findings known in June.
