United Nations officials have found that missiles fired at Saudi Arabia by Yemen’s Houthi militiamen appear to have a “common origin,” but they are still investigating US and Saudi claims that Iran supplied them, according to a confidential report.

The officials traveled to Saudi Arabia to examine the debris of missiles fired on July 22 and Nov. 4, wrote U.N. Secretary-General Antonio Guterres in the fourth biannual report on the implementation of UN sanctions and restrictions on Iran.

They found “that the missiles had similar structural and manufacturing features which suggest a common origin,” said Guterres in the Friday report to the UN Security Council, seen by Reuters on Saturday.

The report comes amid calls by the United States for Iran to be held accountable for violating UN Security Council resolutions on Yemen and Iran by supplying weapons to the Houthis.

Saudi-led forces, which back the Yemeni government, have fought the Iran-allied Houthis in Yemen’s more than two-year-long civil war. Saudi Arabia’s crown prince has described Iran’s supply of rockets to the Houthis as “direct military aggression” that could be an act of war.

Iran has denied supplying the Houthis with weapons, saying the US and Saudi allegations are “baseless and unfounded.”

Guterre’s report said the UN officials saw three components, which Saudi authorities said came from the missile fired on Nov. 4. The components “bore the castings of a logo similar to that of the Shahid Bagheri Industrial Group” - a UN-blacklisted company.

The officials are “still analyzing the information collected and will report back to the Security Council,” wrote Guterres.
