File: Opposition leader Felix Tshisekedi takes over from Joseph Kabila who is stepping aside after 18 years at the helm of sub-Saharan Africa's biggest country.
ADDIS ABABA, Ethiopia - The African Union has cancelled a delegation to the DR Congo over the country's disputed presidential election after the Constitutional Court declared Felix Tshisekedi the victor, an AU source said Sunday.
At a summit on Thursday, AU leaders had cited "serious doubts" about the election figures and called for the final results to be delayed.
The mission to Kinshasa, to be led by AU chairman Paul Kagame, the Rwandan president, and AU Commission president Moussa Faki of Chad, had been set for Monday.
Announcing the final results of the much-delayed poll, the Democratic Republic of Congo's top court threw out a challenge by runner-up Martin Fayulu in an overnight announcement.
It declared Tshisekedi the winner, paving the way for him to take over from the country's longtime leader Joseph Kabila, 47.
The disputed result has raised fears of fresh bloodshed in the vast and volatile central African nation.
