Kenyan police used tear gas to disperse opposition supporters in the capital Nairobi on Wednesday as tensions rise one day ahead of the presidential elections. Kenya's opposition leader Raila Odinga urged his supporters to boycott the elections which are due Thursday claiming they will not be free or fair. He also withdrew from Kenya's upcoming vote after claiming that the electoral commission... Еще had not taken measures necessary to ensure a fair election for the second round. Opposition supporters are angry that the country's presidential election re-run looks set to go ahead despite their calls for it to be postponed. The original election in August was nullified by the Supreme Court following protests and a legal challenge over alleged vote-rigging in favour of the current president Uhuru Kenyatta. After initially calling for protests during polling day, Odinga has since encouraged voters to stay at home and boycott the vote.
