DUBAI — The seizing of Iranian missiles headed for the Iran-backed Houthi militia is “another example of the world’s largest state sponsor of terror the Islamic Republic of Iran continuing to defy the UN Security Council,” US Secretary of State Mike Pompeo said on Friday . The UN-imposed arms embargo on Iran is supposed to expire in October 2020. Pompeo’s announcement follows the US Navy’s announcement Thursday that it had seized 150 Iranian manufactured anti-tank guided missiles after boarding a vessel while conducting maritime security operations in the Arabian Sea. Under a UN resolution, Tehran is prohibited from supplying, selling or transferring weapons outside the country unless approved by the Security Council. A separate UN resolution on Yemen bans the supply of weapons to Houthi leaders. But for years Iran has backed the Houthis, arming them with missiles that are launched across the Saudi-Yemeni border into the Kingdom. — Al-Arabiya English
