At least 25 people were killed in Nigeria when a passenger bus collided with a fuel tanker, triggering a fire that engulfed both vehicles, officials said.

The crash happened on a major highway, one of the country’s busiest transport corridors. Emergency teams rushed to the scene, but the blaze spread quickly, leaving little chance of survival for those trapped inside.

Road crashes are tragically common in Nigeria, where overloaded vehicles, speeding and poor road conditions combine to produce some of the world’s worst accident figures. Fuel tanker explosions in particular have caused repeated mass-casualty disasters.

Officials said an investigation has been launched to determine the cause of the collision. Early reports point to dangerous driving, though the final findings are still awaited.

The accident has renewed calls for tougher enforcement of road safety rules. Authorities have urged drivers of heavy vehicles to follow speed limits and rest requirements, while survivors and families of the victims await news from hospitals and mortuaries.
