There was panic at Kapindasum village in Baringo South sub-county after bandits attacked security officers on Tuesday morning.
The gunmen targeted General Service Unit (GSU) personnel on a routine patrol prompting a fierce gun battle for hours, witnesses and police said.
Officials said the bandits surrounded Kapindasum Primary School and the neighbouring GSU camp as the fighting raged.
There was no death reported by the time of going to press but officials fear there will be casualties.
Officials aware of the incident said a reinforcement had been sent to the area to help push the attackers out of the place.
By the time the incident happened, GSU commandant Eliud Lagat was in a meeting with Environment Cabinet Secretary Soipan Tuya for a tree planting exercise at the Recce company in Ruiru.
He was briefed on the incident and ordered a full response from teams near the area.
The attackers are said to have been targeting livestock in the area when they bumped into police.
The area is among those preparing for national examinations.
The incident comes barely weeks after gunmen fired shots at Kapindasum Primary School as pupils were going to lunch.
The school reopened this year after being closed since 2019 due to incessant attacks.
There is an ongoing joint operation in the area.
The joint Security Operation is led by the National Police Service (NPS) with the assistance of the Kenya Defence Forces (KDF).
Despite a heavy police presence in the marked areas, armed bandits have continued to attack, kill and rob residents before retreating to caves and forests from where they monitor the public and security personnel as they plan further attacks.
