United Nations: The United Nations will not disclose to a Saudi Arabia-led coalition sources of information that led the world body to briefly blacklist it for maiming and killing children in Yemen, a UN spokesman said on Wednesday.

Saudi Ambassador to the UN Abdullah Al Mouallimi, in a June 8 letter on behalf of the coalition to UN Secretary-General Ban Ki-moon, asked the United Nations to reveal details on the sources of information for its report on violations of child rights during armed conflicts.

UN spokesman Stephane Dujarric said the world body has yet to respond to the letter, though he made clear the UN will not disclose details of its sources for the report.

“Protecting the sources of information that are used in this report, or any other report, is paramount, especially in a conflict area,” he told reporters. “But we obviously welcome any information that the Saudi-led coalition may want to share with us.”
