UNITED NATIONS: Iran has violated a UN arms embargo by failing to block supplies to Yemen’s Houthi rebels of ballistic missiles that were fired at Saudi Arabia, a UN panel of experts says, bolstering US and Saudi claims of Tehran’s military involvement in Yemen.

The report seen by AFP on Friday does not identify the supplier but makes clear that missile debris inspected by the experts were of Iranian origin.

“The panel has identified missile remnants, related military equipment and military unmanned aerial vehicles that are of Iranian origin and were introduced into Yemen after the imposition of the targeted arms embargo” in 2015, said the report to the Security Council.

“As a result, the panel finds that the Islamic Republic of Iran is in non-compliance with paragraph 14 of resolution 2216” that imposed the ban on arms sales to Yemen, said the 79-page report presented on Tuesday.

Iran has strongly denied arming the Houthis and last month accused US Ambassador Nikki Haley of presenting “fabricated” evidence that a Nov.4 missile fired at Riyadh airport was Iranian-made.

Haley told the Security Council in December that the United States will push for action against Iran over the missile attacks targeting its ally, but Russia quickly signaled that it would not endorse such plans.

The missile attack on Riyadh airport “changed the tenor of the conflict, and has the potential to turn a local conflict into a broader regional one,” the experts warned.

The panel also said it was investigating whether Iran had sent “advisers” to help the Houthis in their war against the Saudi-led coalition. The UN experts travelled to Saudi Arabia in November and again last month to inspect the remnants of missiles fired by the Houthis in May, July, November and December.

They found that design features of the missile debris were “consistent with those of the Iranian-designed and manufactured Qiam-1 missile” and “almost certainly produced by the same manufacturer.”

The drones were “virtually identical in design” to that of an Iranian-made UAV manufactured by the Iranian Aircraft Manufacturing Industries (Hesa), said the report.

Iran “failed to take the necessary measures to prevent the direct or indirect supply, sale or transfer” to the Houthis of the missiles, storage tanks for propellant and drones, it concluded.
