Chad’s interim President, Mahamat Idriss Deby has won the May 6 presidential election with over 61% of the votes.
Deby was announced as winner of the presidential election by the state election body, on Thursday, citing provisional results, according to Reuters.
His main challenger has declared himself the winner.
Chadians go to the polls on Monday three years after their military leader seized power, but some opposition parties have cried foul over allegations of rigging.
With tensions running high, large numbers of security forces deployed at major intersections in the capital N'Djamena ahead of the results announcement.
According to Reuters, National Election Management Agency chief Ahmed Bartichet said Deby had secured 61.3% of the vote - comfortably over the 50% needed to avoid a run-off.
He said Deby's prime minister and top opposition candidate Succes Masra, 40, had won 18.53%.
Just before the ceremony, Masra claimed victory in a live broadcast on Facebook and called on security forces and his supporters to oppose what he called an attempt to steal the vote.
"A small number of individuals believe they can make people believe that the election was won by the same system that has been ruling Chad for decades," he said.
"To all Chadians who voted for change, who voted for me, I say: mobilise. Do it calmly, with a spirit of peace," he said.
