The defeated opposition candidate in DR Congo's presidential election has vowed to challenge the result in court.
Martin Fayulu told reporters that the people of the nation deserved to know the truth of the election, which he said had led to a coup.
Another opposition candidate, Felix Tshisekedi, was declared the winner amid accusations of a power-sharing deal with the outgoing president.
Several deaths and injuries have been reported in the wake of the results.
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.
The influential Catholic Church, which posted 40,000 election observers, said the result did not match its findings.
Mr Fayulu said he would challenge the declared result in the constitutional court.
I will do whatever is possible for me to do to get the truth because the Congolese want change, he said.
Mr Fayulu admitted such a challenge would have little chance of success as the court was composed of Kabila's people but he said he did not want to give his opponents any chance to say he had not followed the law.
Felix Tshisekedi has been nominated by Mr Kabila to perpetuate the Kabila regime. Because today the boss is Kabila, Mr Fayulu said.
Mr Kabila cannot stay and make an arrangement with someone who will not have any power Mr Tshisekedi knows himself that he did not win.
Mr Fayulu said he feared there would be violence if the electoral commission did not give the true figures polling station by polling station and that it was the right of all Congolese to demonstrate according to the law.
Celebration among protest
Thousands of supporters of Mr Tshisekedi took to the streets to celebrate but those who backed Mr Fayulu also came out in protest.
Violent scenes were reported in Kikwit, where at least two policemen and two civilians were said to have been killed.
There were reports of several hundred students protesting against the result and being dispersed by tear gas in the town of Mbandaka.
Protests were also reported in Kisangani but the south, where Mr Tshisekedi has broad support, was mainly celebrating.
UN Secretary General, Antonio Guterres has urged all sides to refrain from violence and widespread unrest has not yet been reported.
