(CNN) -- Police in Gabon have rescued more than 140 children who were smuggled in from 10 countries to forcibly work in local markets, Interpol said.
The three-day operation, which began on December 11, was led by the international police organization and resulted in the arrest of some 44 people, the agency said Monday.
Officials said they found that children as young as six were working in markets in the capital city Libreville. Interpol did not say which countries the children were taken from.
The nation of about 1.5 million has a per capita income four times that of most sub-Saharan African nations, according to the CIA World Factbook.
