Iran's Revolutionary Guards say two oil tankers hit mines in Strait of Hormuz

Iran’s Revolutionary Guard Corps reported that two supertankers carrying over two million barrels of oil each caught fire after hitting mines in the Strait of Hormuz on October 17, 2026. The incident follows heightened conflict since late February 2026, during which Iran restricted transit and the U.S. imposed a naval counter-blockade. Daily crude flows through the strait plunged from 20.8 million to 2.9 million barrels in October, driving up global energy prices. U.S. President Donald Trump ruled out nuclear options or ground troops, anticipating a diplomatic resolution after November 3, 2026.
