The accident happened at around 7:00 p.m. local time on National Road No. 1, near the village of Yamong in the Kaffrine region, reported the Senegalese Press Agency, citing a security source.
The accident was caused by the overturning of a transport bus after one of its tires burst, the report quoted the source as saying.
The Senegalese government implemented several measures last year to combat traffic accidents following a series of deadly accidents.
