South Korea introduces 'chemical castration' for paedophiles
In South Korea, convicted paedophiles can now face a controversial punishment known as "chemical castration".
A law enacted in July gives judges the power to order sex offenders to undergo drug treatment designed to diminish sexual urges.
The government says the new legislation's aim is to protect children against the increasing number of reported sex crimes.
But for the critics, the practice violates basic human rights.
