The spokesman of the government of the Democratic Republic of Congo (DRC) Lambert Mende launched on Saturday a conviction against the President of the Union for Democracy and Social Progress, Etienne Tshisekedi, who proclaimed himself the president of the country after the official announcement of the victory of incumbent President Joseph Kabila on Friday. \"Tshisekedi created an atmosphere of terror,\" said Mende, adding that the crisis had existed in the DRC since Mr. Tshisekedi proclaimed president in South Africa in November before the election on Nov. 28. \"Figures provided by Tshisekedi are ridiculous,\" said Mende, \"Tshisekedi told the French press that he had obtained 75 percent of votes against 28 percent for Joseph Kabila according to the results.\" According to the results announced by the Independent National Electoral Commission (CENI) on Friday, Kabila won the presidential election with 48.95 percent of the vote while Tshisekedi gained 32. 33 percent. But the opposition leader rejected the results and proclaimed himself president. The government spokesman said the statement was an \"irresponsible act that violates the laws\" and \"We must firmly condemn the self-declaration by Mr Etienne Tshisekedi,\" he told a press conference. \"The public prosecutor has the authority to take the matter to court,\" he warned. Riots took place after the declaration by the CENI in some neighborhoods of Kinshasa, the capital of the DRC, where most inhabitants are in support of Tshisekedi. During the clash in riots, six people have been killed, according to police. Mende stated that the national police did not use real bullet to fire to the demonstrators to disperse them. \"The police did not receive a live bullet, so that they can not shoot real bullet,\" he said.
