The crisis, which started on Thursday, was said to have been caused by a face-off between a Yoruba and Hausa resident.
Speaking when he visited the area in the company of Rotimi Akeredolu, his Ondo counterpart, on Sunday, Makinde promised to give palliatives to those whose businesses were affected during the crisis.
He called on the warring parties to eschew violence, cautioning them that resorting to self-help is not an option.

On his part, Akeredolu said he was in the state on behalf of all the south-west governors to appeal to the people to embrace peace.
He urged the people to think about their family members in other parts of the country and put an end to the crisis.
