Kenyans are anxiously awaiting a Supreme Court decision on whether the country's March 4 presidential election was valid.
The court is expected to issue its decision Saturday, after hearings this week which examined alleged irregularities during the vote-counting process.
Kenya's electoral commission said Uhuru Kenyatta won the election with just over 50 percent of the vote. But lawyers for runner-up Raila Odinga argue that vote totals from some polling stations were altered.
Also, a civil society group says the commission announced Mr. Kenyatta had won before it finished compiling the final vote count.
If the Supreme Court decides the results are not credible, the country will have to hold another election, a possibility that worries many Kenyans.
Ethnic violence sparked by the disputed 2007 presidential vote killed more than 1,100 people and displaced some 600,000 others.
Mr. Kenyatta is facing trial at the International Criminal Court on charges that he helped to organize that violence.
