Are being formed as we speak.
Iraqi children are getting caught up in a growing humanitarian tragedy as violence continues in the country, the UN Children's Fund (Unicef) has warned.
Half of the four million Iraqis who have fled their homes since the conflict began are children.
And the needs of children are outstripping the international aid that has been supplied, the agency said.
More funds were needed, Unicef said, launching an appeal for almost $42m (£21m) over the next six months.
"Violence is creating widows and orphans on a daily basis, many of whom are left to struggle for survival," it said.
"Iraq's children, already casualties of a quarter of a century of conflict and deprivation, are being caught up in a rapidly worsening humanitarian tragedy."
