Peace agreements were Thursday signed by representatives from Borana and Rendile who live in Badasa and Songa.
The deal was brokered by the National Cohesion and Integration Commission under the banner of an Inter-peace initiative in a meeting that brought together county officials, local leaders and senior security officials from the areas.
The communities have become trapped in violence sparked by cattle rustling, inadequate pastures and water.
Marsabit county commissioner Nobert Komora who spoke at the meeting warned criminals that their days are numbered.
"We are not going to tolerate anybody engaged in crime. They should look for somewhere else," warned the commissioner
Under the accords, the signatories pledged to encourage members of their communities to work for peace by forgiving past acts and spreading messages of cohesion and harmonious coexistence.
Komora revealed that they have so far put in place stringent security measures to curb criminal activities.
Komora added that a GSU post will be stationed at the Bank Quarters area where more than 10 people were killed and the officers would patrol along the road.
He called on residents to work closely with the security team to weed out crime in their midst, saying that the security was a collective responsibility.
"We are appealing to residents to volunteer information of any criminal activities. This will help the security team to act swiftly in addressing insecurity," he said
The commissioner promised to engage community elders in efforts to long-lasting peace in the region and urged the residents to support security agencies in the war against crime.
Komora told residents that police reservists manning between Badasa and Songa whose guns were withdrawn would be reinstated.
He warned national government officers including deputy county commissioners against laxity, saying the officers who don't respond to distress calls risk being sacked.
"Those officers who don't perform their work as expected will be dealt with. We cannot watch as people are being attacked and injured." Said commissioner
Marsabit County executive committee member for Administration, cohesion and public relation Armara Galwab said the Rendile-Borana peace accord was meant to usher in an era of peaceful coexistence, stability and development.
"The weapons buried inside the hole signify the end of blood relation and usher in a new chapter of forgiveness, peaceful coexistence and stability among pastoral communities in the region," said Armara.
He said the road to peace was long as trust between the communities was all more fragile, saying that the competition that existed between them over the sharing of natural resources gradually turned into violence.
Armara lauded the decision of the two warring communities for reconciling and called for the involvement of women in peace programmes saying the women are conflict victims.
"We appreciate the signing of this peace agreement between the neighbouring communities. We hope the guns will be silent and they build on peace accords," he said
"There is a need to stamp out cattle rustling for the people to engage in meaningful development for the sake of posterity," he said.
The county executive committee member for Administration said everyone should make concerted efforts to uphold peace and harmony at every cost.
Armara asked security agencies to ensure residents are protected as well as their property.
"We are appealing to security apparatus to deal firmly with criminals who are out to ruin the peace-building initiatives," he said
He asked residents not to hide criminals who wreak havoc in the region, saying that hiding criminals curtailed efforts to improve security.
Sagante Jaldesa ward MCA Amos Wako thanked the Inter-peace Initiative for making efforts to bring warring communities together.
"The peace agreement comes after many efforts to reconcile the warring communities failed," he said
He said everyone has a role to play in making peace with ourselves and our neighbours.
According to Karare MCA Joseph Leruk, peace can only be achieved if one practices, nurtures, embraces and allows it to grow.
While stressing the importance of forgiveness and breaking the cycle of violence, Leruk urged the community not to revenge and instead give security agencies time to investigate and arrest the culprits.
Saku CDF chairman Guyo Bonaya called for the involvement of youth in Peacebuilding initiatives, saying that young people play a vital role in promoting social cohesion.
