Kenyan election officials continue to count ballots from Monday's presidential vote, with provisional results so far showing Uhuru Kenyatta in the lead.
Fewer than half of polling stations had reported when the count resumed Wednesday after a break overnight.
Those results put Kenyatta ahead of his chief rival, Prime Minister Raila Odinga, by a 53-42 percent margin.
Election officials say that nearly 330,000 ballots have been rejected so far for not following voter rules. With the winning candidate required to secure more than 50 percent of all votes cast, some analysts are predicting that Kenyatta will fall short of the threshold and face a runoff election in April.
International observers have said the vote was generally calm.
John Stremlau of the U.S.-based Carter Center, says the group will release its preliminary report Wednesday, praising voters and Kenya's electoral body for a "peaceful" and "very vibrant" election.
"Let's hope that the results, when they become known, will lead to the winner showing generosity to the defeated and the defeated accepting with magnanimity the loss," said Stremlau. "Because I think all Kenyans want to move on and have this become the prosperous, stable country that it's always assumed to be."
