CAPITALS — The UN has agreed to send war crimes investigators to Yemen to examine alleged violations committed by all parties to country's civil war.
The UN Human Rights Council adopted a resolution to set up a group of "eminent" experts.
It was a compromise between Western powers and a group of Arab states that included Saudi Arabia.
A Saudi-led coalition is backing Yemeni pro-government forces in a conflict with the rebel Houthi movement.
More than 8,530 people, 60 per cent of them civilians, have been killed and 48,800 injured in air strikes and fighting on the ground since March 2015, according to the UN.
The conflict has also left 20.7 million people in need of some kind of humanitarian assistance, created the largest food security emergency in the world, and led to a cholera outbreak that is believed to have affected 700 thousand people since April.
Under the deal agreed in Geneva on Friday, a group of "eminent international and regional experts" will carry out a comprehensive examination of "all alleged violations and abuses of international human rights and other appropriate and applicable fields of international law" in Yemen.
It will "establish the facts and circumstances surrounding the alleged violations and abuses, and where possible, identify those responsible".
The resolution was approved after a proposal from some EU states and Canada for a more robust investigation with the formal status of a "commission of inquiry" was withdrawn.
An alternative proposal from the Arab group to send three experts to Yemen to investigate and to engage with a domestic inquiry established by Yemen's government was also shelved.
Saudi Arabia, which had lobbied hard against a commission of inquiry - even reportedly threatening to restrict trade ties with countries which backed it - publicly thanked the UK, US and France for their co-operation in achieving a compromise. The three states also back the coalition's intervention in Yemen.
The weaker resolution may be a disappointment to human rights groups, who had called for a commission of inquiry, the BBC's Imogen Foulkes in Geneva reports.
They allege that war crimes and crimes against humanity are being carried out with impunity in Yemen, and that the conflict is directly responsible for the cholera epidemic.
UN Human Rights Commissioner Zeid Raad Al Hussein had also asked the council to approve a commission of inquiry; his office has doubts that Yemen's domestic inquiry can be impartial.
Earlier on Friday, the International Committee of the Red Cross said "excessive" numbers of civilians were being killed in disproportionate air and artillery strikes carried out by all sides to the conflict.
The ICRC has repeatedly warned of a humanitarian catastrophe in Yemen, and now expects cholera cases to reach 900 thousand by the end of this year.
