Kenya's Supreme Court on Monday dismissed two petitions to overturn the country's October 26 presidential election re-run, validating the poll victory of President Uhuru Kenyatta.

"The court has unanimously determined that the petitions are not merited. As a consequence, the presidential election of 26 October is hereby upheld as is the election of the third respondent," said Chief Justice David Maraga, referring to Kenyatta.
