Kenyan Prime Minister Raila Odinga has filed a Supreme Court appeal against Uhuru Kenyatta’s narrow victory in the presidential election’s first round.
Mr Kenyatta beat Mr Odinga comfortably by 50.07% to 43.28% on 4 March, avoiding a run-off by only 8,100 votes.
But Mr Odinga has accused the electoral authorities of manipulating the result.
Police fired tear gas to disperse about 100 supporters of his Coalition for Reforms and Democracy (Cord) who had gathered outside the Supreme Court.
The police had warned them that they would not be allowed to do so.
