Yemeni authorities seized a boat containing money, weapons, and explosives, including surface-to-air missiles, C-4 explosives, 122-mm shells, rocket-propelled grenades, and bomb-making equipment such as electronic circuits and remote triggers. The weapons were made in Iran, according to U.S. officials, and may have been destined for insurgents inside Yemen. The surface-to-air missiles may be the Iran's Misagh-2.
