The opposition candidate defeated in the presidential election of the Democratic Republic of the Congo promised to challenge the result in court.
Martin Fayulu told the BBC that the people of the nation deserved to know the truth of the elections, which led to a "coup".
Another opposition candidate, Felix Tshisekedi, was declared the winner on charges of a power-sharing agreement with the outgoing president.
Several deaths and injuries have been reported in the wake of the results. [1
The election had to choose a successor of Joseph Kabila, who has been in charge for 18 years.
The result, if confirmed, would be to create the first orderly transfer of power from independence from Belgium in the 1960s.
The influential Catholic Church, which sent 40,000 election observers, said the result does not match his conclusions.
What did Mr. Fayulu say?  9016] Speaking to BBC Africa director Fergal Keane, Fayulu stated that he would challenge the result declared in the constitutional court.
"I will do all I can to do the truth because the Congolese want change," he said
Mr. Fayulu admitted that such a challenge would have little chance of success since the court was "composed of The People of Kabila "but said he did not want to give his opponents any chance to say he had not followed the law.
"Felix Tshisekedi was appointed by Kabila to perpetrate the regime of Kabila, because today the chief is Kabila," Mr. Fayulu said.
"Mr. Kabila can not remain and make an agreement with someone who will have no power … Mr Tshisekedi knows he has not won."
Mr. Fayulu said that he feared there would be violence if the electoral commission did not give the real figures "electoral seat for polling station" and that it was the right of all the Congolese to demonstrate according to the law.
C & # 39; was it violence?
Thousands of supporters of Mr. Tshisekedi took to the streets to celebrate, but those w also supported Fayulu came out in protest
There were violent scenes reported in Kikwit, where at least two policemen and two civilians were killed.
Several hundred students were reported protesting against the result and had been dispersed by the tear gas in the city of Mbandaka.
The protests have also been reported to Kisangani but to the south, where Mr. Tshisekedi has ample support, he was mainly celebrating.
UN Secretary-General Antonio Guterres urged all parties to "refrain from violence" and widespread unrest has not yet been reported.
What was the result of the elections?  According to the National Electoral Commission (Ceni), Mr. Tshisekedi received 38.5% of the votes in the elections on 30 December.
- Felix Tshisekedi – 7 million votes
- Martin Fayulu – 6.4 million votes
- Emmanuel Shadary – 4.4 million votes
The turnout was 48%
 The judges will then have seven days to deliberate.
The constitutional expert Jacques Ndjoli told the BBC that there were three possible outcomes: the court could confirm Mr. Tshisekedi's victory, order a recount, or cancel the results altogether and convene new elections.
The constitutional court has never overturned the results before, and some think that most of its judges are close to the ruling party.
If Mr. Tshisekedi was confirmed as winner, it should be inaugurated within ten days.
How was the result received?
Mr. Tshisekedi saluted his victory, promising to be "the president of all DR Congolese".
His spokesperson, Louis d'Or Ngalamulume, said that "there was never any agreement" with Mr. Kabila.
The ruling party of Kabila, whose candidate reached a distant third, has not yet contested the result, although he did not rule out doing so.
Outside, the answer was a mixture of tempting calm and asking for clarification.
The leader of the African Union, Moussa Faki Mahamat, said that any dispute must be "resolved peacefully, by addressing relevant laws".
The United States greeted the "courageous" Congolese voters and called for a "clarification of the issues raised regarding the electoral count"
The EU called on all parties to refrain from violence.
France challenged the declared result, saying that "it was not consistent with the true results".
French Foreign Minister Jean-Yves Le Drian said, "Faced with this, Fayulu was the leader who came out of this election."
