The move by the Tana River County administration to construct ward administration offices in the contested areas of Fafi and Ijara constituencies has sparked tension in the area.
Tension now remains high in Garissa and Tana River counties over the border dispute that has a long history.
The disputed area is a three-mile-long river strip separating the two counties, mainly due to its value as a source of water and pasture.
The Tana River county administration recently constructed ward administration offices, EECD classrooms and health centres in the disputed areas of Mansabubu, Nanighi, Abalatiro and Masalani.
In response, Garissa deputy county secretary Abdirashid Mohamed expressed concern on the motives of the latest move by Tana River County.
The developments are likely to cause a break in the fragile peace between the two communities living side by side along the disputed boundary.
Governor Korane was addressing the Building Bridges to Unity Advisory Task Force in Garissa town on Friday. The task force is chaired by Garissa Senator Mohamed Yusuf Haji.
Earlier this year, Garissa Governor Ali Korane said that the three-mile-long river strip separating Garissa and Tana River counties should be scrapped.
