The United Nations Security Council is holding a special meeting about the situation in the Democratic Republic of Congo following the announcement of the results of the 30 December presidential election.
Early on Thursday morning, the electoral commission announced that Felix Tshishekedi had won sparking protests from supporters of another opposition figure, Martin Fayulu.
The influential Catholic Church, which says it had forty thousand election monitors across the country, has said that their figures show a different result from the one announced. Several deaths and injuries have been reported in the wake of the results.
Mr Fayulu has said he would challenge the election result in the Constitutional Court.
The election was to choose a successor to Joseph Kabila, who has been in office for 18 years. The result, if confirmed, would create the first orderly transfer of power since independence from Belgium in 1960.
