The U.S. 5^th Fleet revealed that on 8 November it interdicted a vessel “in the Gulf of Oman smuggling lethal aid, including a large quantity of explosive material, from Iran to Yemen”; the four Yemeni crewmembers were repatriated and the ship sunk. A U.S. commander maintained that the 70 tonnes of ammonium perchlorate found abroad “was a massive amount of explosive material, enough to fuel more than a dozen medium-range ballistic missiles depending on the size”. The U.S. statement also highlighted that “the direct or indirect supply, sale or transfer of weapons to the Huthis violates UN Security Council Resolution 2216 and international law”. Iran maintained it had “not taken any action against the resolution, and is actively cooperating with the sanctions committee formed to oversee the arms embargo”.
