With almost half of the results from Kenya's presidential election now confirmed, the two main candidates are running neck and neck.
Deputy President William Ruto has taken a slight lead over ex-Prime Minister Raila Odinga - 51% against 48%.
The electoral commission head has admitted that announcing the result of Tuesday's election has been too slow.
The verification of results has been stopped several times after complaints by supporters of the main candidates.
On Saturday night, Mr Odinga's supporters entered a restricted area and accosted electoral officials, accusing them of tampering with the vote.
Mr Odinga's chief campaign manager was able to get to the lectern used by top electoral commission officials, where he criticised the result verification process.
