Tonight on AC360: Syrian military using children as human shields

Today U.N. Under-Secretary General for Peacekeeping Operations Herve Ladsous said the escalating violence in Syria can now be considered a full-scale civil war. And an alarming new U.N. report outlines the brutality against children at the hands of Bashar al-Assad's forces. Syria was added to the "list of shame" of countries and groups that recruit, kill or sexually abuse children in armed conflicts.

The U.N. special envoy for children and armed conflict, Radhika Coomaraswamy said, "Children as young as 9 years of age were victims of killing and maiming, detention, torture, arbitrary arrest and were used as human shields by the Syrian government forces, including the Syrian armed forces, the intelligence forces and the shabiha militia."

Photojournalist Robert King has documented the suffering of children in one town located in Syria's Homs province. He told Anderson that in all his work as a war photographer, he's never seen anything like it. Watch a preview and see the full interview at 8 and 10 p.m. ET tonight.
