Over 70 people were injured and taken to hospitals, and among the victims who died were nine men and five women.
The Ivorian press agency reported that one of the buses was transporting mourners, including foreigners, to a funeral for a woman who had died in Europe.
The precise cause of the accident is still unknown.
In a statement posted on Facebook, the Ivorian transport minister expressed condolences to the families of the deceased.
The ministry also called on motorists and road users to be more vigilant to avoid such accidents.
Deadly road accidents are common in the West African country amid poorly maintained roads and vehicles. Driver errors also often contribute to the accidents.
