On March 19, 2011 Turkish authorities seized a large weapons cache destined for Syria from an Ilyushin cargo aircraft operated by Yas Air, an Iranian cargo airline. The cargo, which was labeled as "spare auto parts," included AK-47 assault rifles, machine guns and ammunition, as well as 60-mm and 120-mm mortar shells. Following an inspection of the seized weapons, a U.N. Security Council Panel found it to be a violation of Security Council resolution 1747, which prohibits arms exports from Iran. Yas Air is a "civilian arm" of the Islamic Revolutionary Guard Corps (IRGC), according to the United Nations, and a successor to Pars Aviation Services Company, which was sanctioned by the U.N. Security Council in 2007. According to the U.S. Treasury Department, Yas Air has moved IRGC-Qods Force personnel and weapons to Syria.
