A group of charities including Save the Children is ramping up a campaign to have the United Nations name and shame violators of children in war zones.
Save the Children has joined with 20 other charities to call on the United Nations secretary general to name and shame those found to have committed violations against children in conflict.
The UN boss Antonio Guterres is shortly to release the annual report on Children and Armed Conflict.
A UN investigation in August 2018 found that parties to the war in Yemen may have committed war crimes including air strikes which killed thousands of civilians, as well as rape and torture.
In Yemen, 90 per cent of children are living close to high-intensity conflict and two million children are out of school.
In last year's report the "Coalition to restore legitimacy in Yemen" was listed as a group that had put in place measures to protect children, but the charities say this is misleading.
Save the Children policy director Mat Tinkler said publishing an accurate list was a simple and effective way to protect children caught in the conflict in Yemen, by holding those responsible to account.
"Immediate steps must be taken to protect Yemen's children and to hold those who have caused them harm to account," Mr Tinkler said.
"One of the simplest mechanisms to help stop this war on children is for the UN Secretary General to name and shame those responsible in the annual Children and Armed Conflict report."
Save the Children has also called on the Morrison government to do more to protect children in conflict.
