Syrian troops have tortured children and used them as human shields on tanks to prevent attacks by opposition forces, a UN report says.
The report also said rebel forces were using children on the front line.
The UN's Special Representative for Children and Armed Conflict, Radhika Coomaraswamy, told the BBC the organisation was "shocked", calling the situation "extraordinary".
