The Children's Minister James Reilly says the Government is acutely aware of the problem of homeless children, but that it cannot be solved easily.
Mr Reilly is attending the UN Committee on the Rights of the Child in Geneva, where he and colleagues have faced tough questions on children's rights.
Earlier, the delegation said that children living in Direct Provision would not come under the remit of the Children's Ombudsman, to the dismay of the Children's Rights Alliance.
This afternoon, Minister Reilly said solving the problem of over 1,600 children in emergency accommodation was a priority.
He said: "We know we have a serious challenge, we have quanftified it and we have a plan to deal with it and we have made resources available to deal with it.
"But it is not going to be one that can be resolved in the very, very short term."
