On July 13, local time, the Joint Maritime Information Center, supervised by the US Navy, said that the US military will begin implementing a maritime blockade of all Iranian ports and Iranian coastal areas at 20:00 GMT on July 14. The blockade applies to all ships, regardless of what flag they fly. The blockade covers the entire coastline of Iran, including but not limited to Iranian ports and oil terminals. The blockade will not prevent neutral vessels from crossing the Strait of Hormuz to or leaving from non-Iranian destinations. Transportation of humanitarian supplies will be permitted, subject to inspection.
