Adoption of children caught in conflict

If you listened to Network Africa yesterday you may have heard the story about some parents in Sierra Leone alleging that their children, who they'd given up for fostering during that country's civil war, were adopted without their consent.

The parents say they have no idea what happened to the children after they were handed over to a local children's charity.

Their version of events has been disputed by the charity.

But how common is this type of story?

Akwasi Sarpong put that question to Sheema Sen Gupta, child protection officer for Unicef in Ghana.
