Kufuor, who is also the president of Ghana, was supposed to meet Kibaki and Odinga together. That fell through, leaving him to shuttle between them in separate meetings that officials say made little headway.
However, Kibaki reportedly told Kufuor that he had initiated dialogue with opposition leaders and his office said: "Now that peace was returning ... his partially formed government would continue to reach out to Kenyan leaders".
As diplomatic activity continues in Nairobi, Kenyan police fired tear gas to disperse more than 100 female opposition supporters marching towards a church in the capital, Nairobi.
David Kerini, a police commander, said: "They had not notified police about the demonstration.
"We asked them to disperse peacefully, which they refused and we were forced to fire tear gas."
Jacqueline Oduol, the chairman of the Orange Democratic Movement (ODM) women's league, said: "We are calling for truth about what happened to our votes and the votes of Kenyans."
Electoral commission accused
Meanwhile, Kenyans for Peace with Truth and Justice, an umbrella of civil society groups formed after the elections, presented a list of alleged charges to police against electoral commissioners and some staff. The charges include forgery, subverting the rule of law, making out false certificates and the abuse of office.
The groups called for the prosecution of all 22 members of the Electoral Commission of Kenya (ECK) and some commission staff, including vote counters.
Shailja Patel, a member of Kenyans for Peace, which includes the state-funded Kenyan National Commission on Human Rights and the Law Society of Kenya, said: "The electoral process is so seriously flawed that, until that is redressed, and until we have truth and justice about the election, we are not going to have a viable society in Kenya."
But Kibaki said in a speech on Wednesday that he considered questions about the vote and the count "closed".
