Three people have been confirmed killed in an accident on southern Nigeria's Lagos-Ibadan expressway, the busiest inter-state route in the country, the local road safety police said on Saturday, Xinhua reports.
A passenger bus somersaulted many times along the 127 km expressway, causing 11 others to sustain varying degrees of injury on Friday.
Clement Oladele, a sector commander of the Federal Road Safety Corps (FRSC) in the country's southwest region, told reporters that the somersault was preceded by excessive speed, a tyre burst, and the bus driver's subsequent loss of control.
The official said the injured victims were taken to a nearby hospital for treatment, adding the remains of the dead victims were also deposited at a government-owned morgue.
The Lagos-Ibadan expressway connecting Ibadan, the capital of Nigeria's southwestern state of Oyo and the commercial hub Lagos, is also the major route to the northern, southern and eastern parts of Nigeria.
