Weapons provided by Western powers and Iran to the warring sides in Yemen are fuelling the six-year-old conflict, marked by deadly Saudi-led coalition airstrikes and Houthi shelling, UN investigators said on Wednesday.
Coalition airstrikes in the past year may amount to war crimes, while the Iran-aligned Houthi movement carried out killings and other abuses that may also constitute war crimes, they said in a report.
"After years of documenting the terrible toll of this war, no one can say 'we did not know what was happening in Yemen'," said Kamel Jendoubi, chairman of the Group of Experts.
