Abidjan - A senior advisor to Ivory Coast President Laurent Gbagbo on Thursday described the announcement of results by the country's electoral commission showing a victory for the opposition as "an attempted coup." Richard Assamoa's statement indicated that the ruling party was not willing to accept results announced by the head of the country's electoral body.The results showed opposition leader Alassane Ouattara had won with 54.1%. The ruling party had prevented the commission from releasing results for days, with officials loyal to Gbagbo going so far as to disrupt a media conference where the election chief attempted to read out the tallies. Meanwhile the UN Security Council on Thursday warned it would take action against anyone who obstructed Ivory Coast's election process after the announcement of results.The vow of "appropriate measures" - a veiled threat of sanctions - was made after urgent consultations by the 15-nation body on renewed tensions where incumbent Gbagbo lost Sunday's presidential election runoff to Ouattara.The delayed provisional results were announced as the Security Council met.Gbagbo has not yet said whether he will accept the results and his supporters have alleged fraud. At least eight people were killed in shooting outside an office of Ouattara's followers in Abidjan on Wednesday night.
