Sixty-five people have been killed after a lorry overturned near the remote town of Gueckedou in southeastern Guinea.
Reports say a bridge collapsed under the weight of the lorry, which was packed with people and goods on their way to a local market.
There were seven survivors, all of whom were seriously injured. Doctors said eight of the dead were pregnant women.
Police blamed reckless driving, overloading and poor road conditions.
Correspondents say lorries are often used to transport people in remote parts of Africa poorly served by public transport.
