At least 37 people have died from suspected carbon monoxide poisoning at a mining site in Plateau State, central Nigeria, local authorities confirmed.

The victims were reportedly working inside the mine when toxic fumes accumulated in poorly ventilated shafts. Officials believe generator exhaust or other fuel-powered equipment may have released carbon monoxide into enclosed areas, leading to the fatal exposure.

Emergency responders recovered bodies from the site, while investigations were launched to determine the exact cause of the gas buildup. Local authorities said safety standards at informal or small-scale mining operations remain a major concern, particularly where ventilation systems are inadequate. Carbon monoxide is an odorless, colorless gas that can quickly become deadly in confined spaces, often without warning. 

The tragedy has renewed calls for stricter enforcement of mining regulations and improved worker protections in Nigeria’s extractive sector. Further details about the identities of the victims have not yet been released.
