The United States filed a complaint seeking the forfeiture of over 9,000 rifles, 284 machine guns, approximately 194 rocket launchers, more than 70 anti-tank guided missiles, and over 700,000 rounds of ammunition that the U.S. Navy seized during four interdictions at sea, two of which took place in 2021 and two in 2023. The weapons were allegedly being shipped to militant groups in Yemen by Iran's Islamic Revolutionary Guard Corps (IRGC).
