Lagos:
An official says at least 36 people have been killed in a bus crash in which a gasoline tanker exploded in southwest Nigeria.
The explosion happened on Friday afternoon in Nigeria's Edo state.
Federal Road Safety Corps spokesman Jonas Agwu said three people survived the collision between the large bus and the tanker. Agwu said the crash resulted in a fire that burned for hours, making it difficult for officials to know how many people died in the crash.
Nigeria has some of West Africa's worst roads, despite its oil wealth. Massive potholes and poor paving, coupled with aggressive drivers, are blamed for many crashes. World Health Organization data shows Nigeria suffers from one of the world's highest traffic fatality rates.
