Since the April 20 attack, tension has been high in the area.
This has affected the peaceful coexistence between the Borana and Somali communities.
Mr Kamonde appealed to youths and residents not to be divided along tribal and clan lines.
Two people were on Tuesday evening killed while four others were seriously injured following a clash between two groups of herders from Isiolo and Garissa in Garbatulla on the border of the two counties.
A shootout ensued when the group from Garissa was approaching Kasa grazing field in Kinna which is used by the Isiolo herders intending to set up a camp in the area.
