Interpol says more than 140 children have been rescued after being forced to work in markets in Gabon, West Africa.
The agency said the children were taken into care. They were as young as six and from 10 countries.
Gabon police found them selling and carrying heavy goods in market stalls in the capital, Libreville.
The BBC reports children from poor West African families have long been sent to work in oil-rich Gabon.
About 40 people were arrested in a two-day operation earlier this month.
