The Saudi Arabiainfo-icon-led coalition fighting in Yemeninfo-icon was on Friday placed on a UN blacklist for killing and maiming children, drawing fresh calls from rights groups to step up pressure on Riyadh over the conflictinfo-icon.

UN Secretary-General Antonio Guterres decided to add the coalition to the annual list of shame while noting that it had taken some measures to improve the protection of children.

"In Yemen, the actions of the coalition to restore legitimacy in Yemen objectively led to that party being listed for the killing and maiming of children," said a report released along with the list as an annex.

In 2016, the coalition was responsible for 683 child casualties and for 38 verified attacks on schools and hospitals, it said.

Yemen's government forces, pro-government militias, the Huthi rebels and Al-Qaeda in the Arabian Peninsula (AQAP) were also cited, but in a separate section of the list that said they had failed to protect children.

In a statement released along with the report, Guterres said the blacklist was "not only to raise awareness" but also to "promote measures that can diminish the tragic plight of children in conflict."

The UN chief said he was encouraged that some governments were working with the United Nationsinfo-icon to spare children from the horrors of conflict and he voiced hope that "more will follow."

Guterres spoke to Saudi King Salman ahead of the release of the list, which UN officials had shared with Riyadh months earlier to avoid a repeat of the clash that followed the blacklisting last year.

Then UN chief Ban Ki-moon briefly included the coalition to the annual list but was forced into an embarrassing climbdown after Saudi Arabia threatened to cut off funding to UN humanitarian programs.

Ban had publicly complained that it was unacceptable for countries to "exert undue pressure" on the United Nations to avoid scrutiny of its actions.

Saudi Arabia denied that it had pressured Ban and has since insisted that the coalition is respecting its obligations under international humanitarian law.

Saudi Ambassador Abdallah al-Mouallimi scheduled a news conference at the United Nations for Saturday.

The report and the list were today sent to the Security Council, which includes countries such as the United Statesinfo-icon, Britaininfo-icon and Franceinfo-icon that support the coalition in its warinfo-icon against Iraninfo-icon-backed Huthi rebels.

Human Rightsinfo-icon Watch applauded the decision to include the coalition on the list but disputed the view that the military was taking measures to protect children.
