Marsabit County Commissioner Isaiah Nakoru confirmed that armed militia from Borana communities engaged their rivals from Burji and Gabra for more than four hours at Olale area Odha location in Marsabit.
He said the security arm of the government could not be able to establish the exact number of those killed in the incident but estimated it to be between ten and twelve from both sides of the rival communities.
Nakoru said heavily armed militia from both sides of the communities clashed in the morning until late in the afternoon.
He said the militia were using sophisticated weapons including machine guns, hand grenade and mortars forcing communities to flee the areas.
He confirmed that those killed and injured were all men.
Thousands of families, mostly women, children and the elderly have fled the border town, following alleged rumors of impending retaliation.
Moyale divisional police commander, Nehemiah Lagat said hundreds of officers have been deployed to the areas to contain the situation.
The killings comes barely two days after a Moyale county staff was slaughtered, a home guard shot at Karare in Marsabit while hundreds of families fled their homes for fear of revenge.
