A view of the gate of the Red Sea port of Hodeidah, Yemen, Aug. 5, 2018 UNITED NATIONS — The UN Security Council met behind closed doors Friday after a Saudi-led coalition attack on a bus carrying children in Yemen, diplomats said.

The meeting was requested by Bolivia, the Netherlands, Peru, Poland and Sweden, which are all non-permanent council members.

The Saudi-led coalition earlier announced that it had ordered an investigation into the airstrike on Thursday that killed at least 29 children traveling on the bus in Yemen.

“We have seen the images of children who died,” Dutch Deputy Ambassador Lise Gregoire-van Haaren told reporters. “What is essential at this moment in time is to have a credible and independent investigation.”

It remained unclear whether the council would unite and call for action. Kuwait, also a non-permanent council member, is a member of the coalition fighting Huthi rebels in Yemen.

Council statements are agreed by consensus, which means any of the 15 members can block a proposed draft demanding an investigation.

The United States, France and Britain — three of the five permanent council members — have supported the Saudi coalition in its military campaign, but have expressed concern over the heavy toll on civilians.

The UN General Assembly approved former Chilean President Michelle Bachelet as the next UN human rights chief by acclamation.

Bachelet will replace Jordanian diplomat Zeid Ra’ad al-Hussein and begin her four-year term starting 1 September 2018 and expiring 31 August 2022.

UN Secretary-General Antonio Guterres on Wednesday proposed to appoint Bachelet for the key post of High Commissioner for Human Rights that is headquartered in Geneva.
