Islamic State militants continue to defy international humanitarian laws by selling abducted Syrian and Iraqi children as sex slaves, torturing them, and crucifying and burying them alive, a United Nations watchdog reported on Wednesday.
The abducted children are mostly from Christian communities and some are Shi'ites and Sunnis.
"We are really deeply concerned at the torture and murder of those children, especially those belonging to minorities, but not only from minorities. The scope of the problem is huge," UN Committee expert Renate Winter told the press.
According to Reuters, the UN Committee on the Rights of the Child said that the militants have been using Iraqi boys aged under 18 as suicide bombers, bomb makers, informants or human shields to protect facilities against US-led air strikes.
"Children of minorities have been captured in many places... sold in the market place with tags, price tags on them, they have been sold as slaves," Winter said, giving no details.
