In China two men have been executed after being convicted of abducting and trafficking 15 children. China's Supreme Court said the trade in stolen children, carried out by organised gangs, was on the rise. Parents, unable to have sons of their own, buy boys from the traffickers for around £3,000 each.

The BBC has obtained rare footage of Chinese police who are trying to curb the trade, but many thousands of children are being snatched off the streets to be sold every year and most are never recovered.
