Kenyan police have killed at least 11 people in a crackdown on protests as anger at the re-election of President Uhuru Kenyatta erupted in the western city of Kisumu and slums surrounding the capital, officials and witnesses said on Saturday.
But in a quick rejoinder, the incoming Nairobi Governor said the opposition leader, who is coming off a presidential election defeat to President Uhuru Kenyatta, has no mandate to make such a declaration.
The 55-year-old Kenyatta will be serving his second and final five-year term in office in line with the requirement of the Constitution.
After he was declared the victor of Kenya's presidential race, President Uhuru Kenyatta called for unity amid the disputed election and reports of protests and violence from the opposition.
USA ambassador Robert F. Godec said any disputes should be dealt with through legal channels. "I extend a hand of friendship and partnership as Kenyans want us to succeed, Asanti Sana".
However, Odinga has defied calls for calm after he called for a strike to support his claim to the presidency and accused the ruling party of "spilling the blood of innocent people". Like in any competition, there is a loser and a victor.
"We have seen the results of political violence".
The Kenyan authorities must investigate reports that police shot dead demonstrators protesting against the outcome of the presidential election last night, said Amnesty International today as protesters started gathering again in opposition strongholds.
Top Odinga lieutenant Johnson Muthama told Reuters police proceeded to pack corpses into body bags before dumping them.
Protests erupted in Odinga's strongholds in western Kisumu county and poor areas of Nairobi nearly immediately after the election results were declared Friday, with gunshots ringing out and fires in the streets.
Global observers including the African Union said the election was free and fair and called on disputes to be resolved through the courts.
The dispute led to a spate of ethnic violence that led to the death of 1,200 people and displaced some 600,000.
On August 11, Kenya's incumbent President Mr Kenyatta was declared the victor of the country's Presidential election.
