Some election officers are protesting non-payment of their training allowances in Kano State.
Media Talk Africa reports that they blocked voters from accessing the polling units.
The INEC ad-hoc staff, in their numbers, said they were not paid their training allowances of N4000.
They vowed that they would not allow election materials to be taken away.
The incident, which occurred at Gwale Local Government of Kano State, delayed commencement of voting at the Dorayi Karama voting centres.
