Riyadh has said it would not oppose an UN inquiry into war crimes in Yemen, but stressed such a probe would face "tremendous obstacles" over access. The Saudi Arabia-led coalition is accused of indiscriminate bombing.
Saudi Arabia's ambassador to the United Nations on Wednesday questioned the timing of an international inquiry into rights violations in Yemen, saying "conditions on the ground" would hamper the investigation.
The UN Human Rights Council is considering an independent, international investigation of rights violations in war-torn Yemen, where Saudi Arabia is leading an offensive against the Iran-aligned Houthi movement.
"We are working together to hopefully come to a compromise," said Abdulaziz Al-Wasil, Saudi Arabia's envoy to Geneva.
"We have no objection to the inquiry itself, we just have a discussion about the timing, whether this is the right time to establish an international commission, with the difficulties on the ground," said Al-Wasil.
"They will face tremendous obstacles in terms of access," he added.
Canada and the Netherlands are backing the idea of an international inquiry, but Al-Wasil said a national investigation by Yemen's National Commission would be preferable. The commission reports to Yemeni President Abd-Rabbu Mansour Hadi who is backed by the Saudi-led coalition.
UN human rights chief Zeid Ra'ad al-Hussein, who has long supported an independent international inquiry, says Yemen's National Commission is not capable of carrying out the task. Zeid said the coalition had shown "minimal efforts made towards accountability."
The Saudi-led coalition on Tuesday said its own investigation showed that a series of deadly airstrikes it had carried out in Yemen had been largely justified.
Saudi Arabia and allies have been bombing the Houthi movement, including the capital Sanaa, since 2015 and the conflict has claimed more than 10,000 lives in total. The Houthis, who control most of northern Yemen, have meanwhile fired rockets towards Saudi cities and villages.
