A ship seized by Yemeni authorities last month was found to be carrying a wide variety of Iranian-made weapons, including material for bombs and suicide belts, explosives, Katyusha rockets, surface-to-air missiles, rocket-propelled grenades and large amounts of ammunition.

Yemen's coast guard intercepted the ship in an operation coordinated with the U.S. Navy. Yemen has recently witnessed several cases of illegal arms shipments through its porous shores on the Red and Arabian seas. Yemen is home to an active branch of al-Qaeda, which staged several failed or foiled attacks on U.S. territory over the past several years.
