USNI News – The U.S. reserves the right to search any Iranian vessels, sanctioned vessels and ships suspected of carrying a list of contraband items, according to a Thursday notice to mariners from U.S. Central Command. Contraband items include weapons, ammunition, explosives and military equipment, the notice reads. Conditional contraband –meaning contraband for aiding Iran’s military operations – includes crude oil, nuclear material, metals and machinery. A full list is included in the blockade update. To that end, the U.S. will pursue ships outside of the U.S. Central Command area of response, Chief of the Joint Staff Gen. Dan Caine told reporters Thursday.
