Syrian authorities are systematically detaining and torturing children, the United Nations' human rights chief, Navi Pillay, has told the BBC.

Ms Pillay said President Bashar al-Assad could end the detentions and stop the killing of civilians immediately, simply by issuing an order.

Syria has accepted a peace plan, amid scepticism about its intentions.

The BBC's Fergal Keane reports.
