United Nations Secretary-General Antonio Guterres has added Israel's military to a global list of offenders who have committed violations against children, said Israel's U.N. envoy Gilad Erdan, describing the decision as "shameful," Paralel.Az reports citing Reuters.

Erdan said he was officially notified of the decision on Friday. The global list is included in a report on children and armed conflict that is due to be submitted to the U.N. Security Council on June 14.

Israel's Foreign Minister Israel Katz said the decision would impact the country's relations with the United Nations.

Erdan said he was notified by Guterres' chief of staff and posted a video on social media of him responding to the decision during their phone call.

"I am utterly shocked and disgusted by this shameful decision of the Secretary-General," said Erdan. "Israel's army is the most moral army in the world, so this immoral decision will only aid the terrorists and reward Hamas."

Guterres spokesperson Stephane Dujarric declined to comment.
