Guterres told the Security Council on Tuesday the United Nations examined debris of weapons used in attacks on a Saudi oil facility in Afif in May, on the Abha international airport in June and August and on the Saudi Aramco oil facilities in Khurais and Abqaiq in September.
“At this time, it is unable to independently corroborate that the cruise missiles and unmanned aerial vehicles used in these attacks are of Iranian origin,” he wrote in the report, seen by Reuters.
The attacks, which hit Aramco’s oil facilities in Khurais and Abqaiq in east of Saudi Arabia on September 14, were claimed by Yemen’s Houthi Ansartullah movement but the kingdom and the US were adamant to blame it on Iran without evidence.
Iran has rejected the allegations of any involvement and said the attack was a legitimate act of self-defense by Yemen, which has been under incessant strikes by the Saudi-led coalition since 2015.
