Two supporters of an Ivory Coast minister were killed in a clash near his home in the central town of Toumodi after President Alassane Ouattara was re-elected to a disputed third term, a ruling party official said on Wednesday. "Two young people from the minister's entourage who wanted to help the minister's brother were shot dead" Tuesday night, Ouattara's RHDP party spokesman Mamadou Toure said. Tensions are high in Ivory Coast after Ouattara was declared victor on Tuesday. Security forces surrounded the homes of his chief rivals after they rejected the election and vowed to set up a rival "transitional government." The United Nations has called for dialogue after election violence claimed more than 40 lives since Ouattara announced in August that he would run again. The crisis has stoked fears the West African state could slide into the kind of violence that killed 3,000 people a decade ago when then president Laurent Gbagbo refused to accept defeat by Ouattara. Police have blocked access to the residences of Ouattara's main adversaries, Henri Konan Bedie and Pascal Affi N'Guessan, after officials accused the opposition of plotting an act of sedition. pgf-pma/ri
