In a tweet posted on their official Twitter page, ODM claimed that the Kiems kit were slow and it was affecting voters.
"IEBC even a small exercise as a by-election you cannot manage your KIEMS kits."
"Why would a voter take a whole thirty minutes to VOTE. Fix up this mess haraka sana," the statement from ODM read in part.
Voters also protested as one KIEMS kit failed at Jamhuri primary polling station.
Reports indicated that IEBC officials are working on sorting out the issue.
