Iran's Islamic Revolutionary Guard Corps (IRGC) attacked U.S. steel and aluminum plants in the Middle East, Iran's Tasnim news agency reported on the 2nd.
The Revolutionary Guard said in a statement, "The 90th operation of the fourth phase of the Promise of Truth has been carried out, and we attacked U.S. steel and aluminum corporations in the region." It appears to be retaliation after the United States and Israel bombed steel mills in Iran on the 27th.
The "U.S. steel and aluminum corporation facilities" Iran mentioned are more likely to be Ras Al Khair, a joint facility in Saudi Arabia, or large smelting facilities in the United Arab Emirates (UAE) or Bahrain where U.S. capital and technology are concentrated, rather than facilities solely owned by actual U.S. corporations. The extent of damage to the facilities is not yet known.
Meanwhile, Agence France-Presse (AFP) reported that steel mills in Iran hit by massive U.S.-Israeli airstrikes have completely halted operations. Khuzestan Steel and Mobarakeh Steel, Iran's two major steel corporations, said they stopped operations after multiple airstrikes by U.S. and Israeli forces recently. Mobarakeh Steel in Isfahan Province in central Iran also said "the production line has been completely shut down due to heavy bombardment."
