Five armed men have attacked Galole tallying centre in Tana River where the counting of votes from the various polling stations was ongoing.
The five knife-wielding attackers stormed the centre, stabbed one person to death and injured several others.
The incident caused tension and disrupted the tallying exercise as IEBC officials and agent scampered for safety.
Police quickly moved in shooting dead two of the assailants while three others managed to escape on foot.
Coast Police boss Larry Kieng confirmed the attack assuring that police had launched a manhunt for the attackers.
"We understand that the tallying exercise is ongoing and if some leaders have sensed defeat and want to misuse the youth then they should know that we will deal them accordingly," he warned.
