The passengers were mostly traders headed to a market in neighboring Edo State, said Kingsley Fanwo, the Kogi state commissioner for information. Kogi state government will work with federal agencies to improve waterway safety and prevent a repeat of such accidents, Fanwo said. Boat accidents are common during the rainy season in remote areas of Nigeria, Africa’s most populous country. At least 31 people were killed last month when an overloaded boat hit a tree trunk in the Borgu area of Niger state.
