Kenyan opposition to file petition against presidential vote
Hundreds of supporters of Kenya's opposition coalition have gathered around the supreme court building in Nairobi where lawyers are expected to file a petition contesting President Uhuru Kenyatta's re-election.
Riot police have been chasing the supporters away, but they keep returning to hold peaceful protests.
Nairobi police chief Japheth Koome said police want to ensure the court building is secure.
Opposition leader Raila Odinga has rejected official results from Kenya's electoral commission, which said Mr Kenyatta won by a margin of roughly 1.4 million votes.
Mr Odinga has claimed, without providing proof, that hackers used the identity of a slain election official to manipulate the result in Mr Kenyatta's favour.
Friday is the deadline for filing court petitions contesting the August 8 election.
