The <a href="https://www.thenationalnews.com/tags/us/" target="_blank">United States</a> is seeking to keep more than one million rounds of ammunition that the <a href="https://www.thenationalnews.com/uae/2022/12/03/us-warship-makes-huge-arms-bust-on-iran-yemen-smuggling-route/" target="_blank">US Navy seized in December</a> as it was in transit from Iran’s Islamic Revolutionary Guard Corps (<a href="https://www.thenationalnews.com/tags/irgc/" target="_blank">IRGC</a>) to militants in Yemen, the Justice Department said on Friday. “The United States disrupted a major operation by Iran’s Islamic Revolutionary Guard Corps to smuggle weapons of war into the hands of a militant group in Yemen," Attorney General Merrick Garland said in a statement. "The Justice Department is now seeking the forfeiture of those weapons, including over 1 million rounds of ammunition and thousands of proximity fuses for rocket-propelled grenades." US naval forces on December 1 intercepted a fishing trawler smuggling more than 50 tonnes of ammunition rounds, fuses and propellants for rockets in the Gulf of Oman along a maritime route from Iran to Yemen, the Navy said. They found more than one million rounds of 7.62mm ammunition; 25,000 rounds of 12.7mm ammunition; nearly 7,000 proximity fuses for rockets; and more than 2,100 kilograms of propellant used to launch rocket propelled grenades, it said. The forfeiture action is part of a larger government investigation into an Iranian <a href="https://www.thenationalnews.com/world/us-news/2023/02/01/thousands-of-yemen-bound-weapons-seized-centcom-announces/" target="_blank">weapons-smuggling network</a> that supports military action by the Houthi movement in Yemen and the Iranian regime’s campaign of terrorist activities throughout the region, the Justice Department said. The forfeiture complaint alleges a sophisticated scheme by the IRGC to clandestinely ship weapons to entities that pose grave threats to US national security. US and British naval ships have made numerous seizures of <a href="https://www.thenationalnews.com/mena/2023/03/06/iran-sending-gifts-of-death-to-yemen-official-says/" target="_blank">weapon shipments</a> believed to be intended for the Houthis, who triggered a devastating civil war in Yemen after seizing the capital in 2014 and forcing the internationally recognised government into exile. <i>With reporting from Reuters</i>
