On January 12, a leaked UN report confirmed that Yemen’s Houthi rebels were using missiles of Iranian origin. The investigating panel writes that they had “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. Referring again to the UNSC arms embargo, the report says these findings show “the Islamic Republic of Iran is in non-compliance with paragraph 14 of resolution 2216 in that it failed to take the necessary measures to prevent the direct or indirect supply, sale or transfer of missile and unmanned aerial vehicles to the Houthi-Saleh alliance.” The 79-page report also criticizes Saudi Arabia and its coalition allies for failing to minimize civilian casualties in the Yemen conflict.
