Kenya’s electoral commission has denied opposition claims its IT system had been hacked in order to manipulate Tuesday’s election results.
Chief electoral officer Ezra Chiloba told reporters the systems were not compromised at any point.
He spoke out after presidential candidate Raila Odinga rejected provisional results indicating a strong lead for President Uhuru Kenyatta.
The opposition’s claim led to sporadic outbreaks of violence.
Mr Chiloba said his team had “established that the claims being made could not be substantiated”.
He added: “I wish to take this opportunity to confirm that our elections management system is secure. There were no external or internal interference to the system at any point before, during or after the voting.”
His comments were made amid repeated calls for calm. Many fear a repeat of the violence after the disputed election 10 years ago when more than 1,100 Kenyans died and 600,000 were displaced.
After this year’s vote, two protesters were shot dead in Nairobi, where police also fired tear gas at crowds who burned tyres and blocked roads throughout the day.
The city’s police chief Japheth Koome said the young men had tried to “attack our officers with pangas (machetes) and that’s when the officers opened fire on them”, according to a news agency.
In another incident, regional police chief Larry Kieng confirmed officers killed two men in the western town of Kisumu, an opposition stronghold.
They were allegedly part of a gang which attacked a vote tallying station, stabbing one man. The motive was not known.
