The stage is set for another bloody showdown in Kenya tonight, with tens of thousands of people about to join a protest in support of opposition leader Raila Odinga. They'll demand the resignation of President Mwai Kibaki, accusing him of rigging last week's election that saw him returned to office. Since then, at least 100,000 people have been driven from their homes in violence that's left hundreds dead. And hopes of mediation are fading, with an international delegation led by the African Union today calling off a proposed visit to Nairobi.
Kenya's security forces already on the streets, trying to stop opposition supporters from a poverty-stricken suburb of Nairobi joining tonight's protest in the city centre. Much of the vast slum has been torched during clashes with government supporters. Opponents of President Mwai Kibaki have been encouraged by a newspaper report quoting the head of the Electoral Commission, saying he didn't know who won the poll, and that he'd announced the result under pressure. And many residents are determined to join the rally in support of Raila Odinga.
KENYAN MAN: We are saying, "No Raila, no peace." There can be no peace in Kenya unless Raila is the President of Kenya.
KENYAN WOMAN: We are going.
REPORTER: And you're ready to risk your lives?
KENYAN WOMAN: Yeah. We are going to risk our lives because if we are dying, we are dying because of this guy who is denying us our change.
Mr Odinga has brushed aside the government's threat to use tear gas and live bullets to break up illegal rallies.
RAILA ODINGA, KENYAN OPPOSITION LEADER: Is just the beginning of what I think is going to be a long, drawn-out process.
He's also ruled out direct talks.
RAILA ODINGA: Now, how can you go and deal with a thief? We are not interested in talking to Kibaki without an international mediator.
But hopes of outside mediation have faded with the news that a scheduled visit to Nairobi by the African Union leader for crisis talks is now in doubt. The US Secretary of State is spearheading the international push for calm.
DANA PERINO, WHITE HOUSE SPOKESPERSON: I know she is reaching out to them again today to try to urge them to ask their followers to refrain from any violence.
Much of the violence has been between the Kikuyu tribe, which supports the President, and the Luo tribe, which backs the opposition. They're trading accusations of genocide.
RAILA ODINGA: What is happening is genocide on a grand scale, because we are seeing the security forces of Mr Kibaki shooting innocent civilians.
KIVUTHA KIBWANA, LANDS MINISTER: All the perpetrators of these crimes must be made aware that genocide is a crime against humanity punishable more severely under both Kenyan and international law.
Kenya's Tourist Board says the industry hasn't been badly affected. But there have been clashes in Mombasa, the main centre for the country's popular international beach resorts. There are also fears for the thriving horticulture and agriculture sectors. And, as refugees flooded into Uganda, its army was deployed along the border to prevent the unrest spreading. Ross Cameron,
