Iran live updates: Trump says war will end, gas prices to fall after the midterms

The United Kingdom Maritime Trade Operations (UKMTO) Centre said that it received a report of a tanker being attacked in the northern Persian Gulf on Wednesday morning.

The tanker was hit by an "unknown projectile" south-east of Al-Faw, Iraq, the UKMTO alert said. "Crew are reported safe and there is no environmental impact reported at this time," the UKMTO added.

Also on Wednesday, the UKMTO issued another report of a vessel spotted listing off Port Rashid in the United Arab Emirates, "possibly indicating water ingress following an attack from an unknown projectile."

Iran on Wednesday condemned the latest U.S. attacks on Iranian oil tankers and said its subsequent strikes on regional U.S. targets were in self-defense.

"The aggressive actions by the United States against Iranian commercial vessels not only represent a dangerous escalation of tensions in the region but also constitute an outright threat to regional and international peace and security," the Iranian Foreign Ministry said in a statement.

The ministry said its subsequent "defensive strikes" targeted "U.S. military bases and facilities located in Jordan that continue to support U.S. military aggressions against Iran, as well as several U.S. aggressive vessels."

Iranian forces, it added, "will not hesitate to exercise their inherent right of self-defense and will respond decisively and appropriately to any enemy military aggression."

U.S. Central Command on Wednesday denied that Iranian forces had struck two U.S. Navy destroyers operating in the Middle East, following claims of a successful attack by the Islamic Revolutionary Guard Corps published by state-aligned media in Iran.

The IRGC claim of a successful strike "is completely FALSE," CENTCOM said in a post to X.

"No U.S. Navy warship has been struck; all IRGC attempted attacks failed. Meanwhile, U.S. forces have successfully destroyed 10 Iranian tankers in just the last week. These vessels were part of a multibillion-dollar shadow network that funds the IRGC, and Iran cannot defend them."

The price of global oil hit $100 a barrel on Wednesday morning, the first time the price reached that threshold since July 24.

Brent crude oil prices, a benchmark for global trading, climbed by about 2.7%, trading at about $100.57 a barrel for contracts with November dates.

U.S. oil traded at about $95 a barrel, up by about 2%.

The price of global oil has been rising throughout the week amid intensified exchanges between the U.S. and Iran centered on the Strait of Hormuz, plus an escalation of fighting between Iran-backed Houthi rebels and Saudi-backed government forces in Yemen.
