Iranian state media said the solid-fueled Qassem Basir ballistic missile represents a new doctrine under which Tehran would act against threats before they are carried out. The report followed comments by Mohsen Rezaei, head of Iran’s Supreme National Security Council, who claimed the missile capability had been tested against a U.S. warship, although it was unclear whether the test involved the Qassem Basir. The U.S. said ballistic missiles were launched at its warships on Saturday and that it struck three Iranian oil tankers in response; the warships evaded the attacks. Washington rejected Rezaei’s plans for an Iranian exclusion zone near the Strait of Hormuz, while maintaining a blockade of Iranian ports. Shipping through the waterway has fallen sharply, and Gulf officials warned against allowing any single country to control the route.
