ISIS putting price tags on Iraqi children, selling them as slaves, U.N. says

ISIS is subjecting Iraqi children to a series of horrors, including putting price tags on them and selling them as slaves, the United Nations said.

In a report released this week, the world body accused ISIS of increasingly using children in its bloody campaign of terror.

It said the terror group's list of brutality is growing longer, and includes enslaving, raping, beheading, crucifying and burying people alive.

"We have had reports of children, especially children that are mentally challenged, who have been used as suicide bombers, most probably without them even understanding what has happened or what they have to expect," said Renate Winter, expert on the U.N. Committee on the Rights of the Child.

Some as young as age 8 are getting training to become soldiers, she said.

"Children of minorities have been captured in places where the so-called ISIL has its strength, have been sold in market with taps, price tags on them, have been sold as slaves," Winter said.

Yazidi children may be among the minorities targeted. ISIS has singled out Yazidis in the past, and they have long suffered persecution, with some Muslims referring to them as devil worshippers.

The U.N. urged Iraq to do more to protect all children, and said the nation's forces are contributing to the problem.

A "very large number of children" have been killed and severely injured by airstrikes, shelling and military operations by Iraqi forces, the report said.

ISIS, or the Islamic State in Iraq and Syria, now refers to itself as the "Islamic State." Some government agencies use ISIL, or the Islamic State in Iraq and the Levant.

Last year, the terror group declared that it had established a "caliphate" spanning Iraq and Syria. Since then, it has gone on a murderous rampage that has included beheadings of foreigners. Hundreds of thousands of Iraqis have fled areas it has seized.

In one of its most recent attacks, ISIS released a video Tuesday showing a Jordanian captive, pilot Lt. Moath al-Kasasbeh, burned to death. The Middle East nation hit back Thursday, unleashing fighter jets to ISIS strongholds in retaliation.

ISIS captured the 27-year-old al-Kasasbeh after his F-16 fighter jet crashed near Raqqa on December 24. Even though the video came out this week, Jordanian authorities say they believe he was killed a month earlier.

The video of the pilot's burning seems to support the U.N.'s assertion.

In it, a young boy looks up as if in awe and says he would "burn the pilot" himself if he had a chance. "All Arab tyrants should also be burned," the boy says.
