Kenya's president says he "personally disagrees" with the Supreme Court ruling that nullifies his election win last month, but he says he respects it.

However, President Uhuru Kenyatta has lashed out at the judges, saying that "six people have decided they will go against the will of the people."

Kenyatta is addressing the nation after Friday morning's ruling that also called for a new election within 60 days. The court says the election commission "committed illegalities and irregularities" after opposition leader Raila Odinga challenged the vote.

The president is calling on Kenyans repeatedly to remain peaceful in a country where some elections have been followed by deadly violence.
