The Moyale peace team faces a tough task in its bid to end conflict after three people were killed and more than 300 camels stolen at Hantut village.
The three Gabra herdsmen were attacked by their Borana neighbours last week.
Marsabit County Police Commander Benjamin Kogo said the attack was sparked by a dispute over resources.
The two communities have been locked in a protracted dispute, with each one claiming ownership of the area.
“We have left the matter to the 35 elders in the peace committee,” said Mr Kogo.
He said, however, as police, they were conducting their own investigations since a crime had been committed.
“As elders are busy arbitrating on the issue, we will continue with investigations. So far no arrests have been made,” he added.
The killings occurred as Marsabit County’s elected leaders and Moyale Peace Committee members met early last week at a hotel in Moyale town for another round of talks aimed at strengthening ongoing reconciliation efforts.
North Horr MP Chachu Ganya described the killings as unfortunate. “The killings happened on June 18 at a time when President Kenyatta was supposed to visit Moyale to launch a resettlement programme for victims of ethnic clashes in the area,” said Mr Ganya.
About 1,500 families affected by the clashes in Moyale are set to benefit from Sh400 million in compensation from the national government.
The Marsabit county government has allocated Sh100 million for reconstruction, security and other infrastructural support in the area.
The Moyale conflict saw President Kenyatta set up a mediation team led by former Speaker of the National Assembly Francis ole Kaparo and Garissa Senator Yusuf Haji.
