Pregnant teenagers freed from 'baby factory'

Police in Nigeria have raided what they say is a child trafficking facility in south-eastern Rivers State.

They say they rescued four pregnant teenagers and more than 20 children between the ages of one and four.

They arrested three people suspected of running what is known locally as a "baby factory" where young women are held until they give birth.

Their babies are then sold to other families.

Dozens of children and young women have been freed from such facilities in recent months, mainly in southern Nigeria.
