Babies are being openly sold online in China

An illegal market in children has developed in China, in which babies are being openly sold online.

Police say many of the victims are from the estimated 20,000 children abducted each year - a crime with a devastating impact on separated children and parents.

This video, which some viewers may find upsetting, shows a baby being offered for sale, during a mobile phone video call with a member of the BBC team.
