Lagos - Seventeen people died and 10 others were injured when the buses in which they were travelling in central Nigeria collided with a tanker lorry, a road safety official said on Saturday.
"The accident happened on Friday morning when two buses travelling from Lagos to Katsina (north) collided with an empty tanker lorry. Seventeen people - all men - died on the spot while 10 others were injured," the head of the Federal Road Safety Commission in Kwara state, Mary Wakama, told AFP.
She said two of those injured were in a "critical" condition.
The accident happened at a village near Ilorin, the state capital, she said, adding that driver fatigue may have contributed to the accident.
Nigeria, Africa's most populous nation, has one of the worst road accident records in Africa, with poor roads, badly maintained vehicles and reckless driving conspiring to kill thousands every year.
