U.S. forces struck three Iranian crude oil tankers on Saturday, Sept. 5, after Iran’s Islamic Revolutionary Guard Corps launched ballistic missiles toward two U.S. Navy warships, according to a U.S. Central Command release. CENTCOM says an aircraft carrier and a guided-missile destroyer evaded multiple attacks and that no American personnel came to harm.

CENTCOM says it permanently disabled the M/T Downy off Kharg Island and the M/T Stark 1 near Jask, and destroyed the unladen M/T Kylo, also known as the “Noxen,” in the Gulf of Oman after directing its crew to abandon ship. It describes the tankers as part of a shadow network that funds the IRGC and its regional proxies. “If you shoot at two of our ships, we will impose an even higher economic cost —taking out three of yours,” CENTCOM commander Adm. Brad Cooper said.

Iran’s Foreign Ministry condemned the strikes as “illegal and aggressive” and accused Washington of waging a naval blockade and economic war against Iran, NBC News reports. Iran’s semiofficial Fars agency said the IRGC fired ballistic missiles at an aircraft carrier and a destroyer that it said had joined the blockade while “harassing Iranian vessels,” and Tasnim reported no casualties aboard a tanker hit near Kharg, according to NBC. Neither side’s account of the missile fire has independent confirmation in the reports this desk read.
