KINSHASA, Congo (AP) — Congo's Constitutional court confirmed the victory of Felix Tshisekedi, dismissing the claims of massive vote fraud by runner-up Martin Fayulu.

Tshisekedi's supporters celebrated the court decision, announced early Sunday, by driving their motorcycles and cars in a procession through Kinshasa. Later the capital city was quiet, with people attending church. Other cities across Congo were also reported to be quiet.

But Fayulu's declaration that he is Congo's "only legitimate president" and call for the Congolese people to peacefully protest what he called a "constitutional coup d'etat" threatened to keep the country in a political crisis that has been simmering since the Dec. 30 elections.

Tshisekedi welcomed the court's decision confirming him as the winner of the presidential election saying it was a victory for the entire country.
