TEHRAN — Iran’s Islamic Revolutionary Guard Corps said Wednesday that it launched a missile attack against a U.S.-linked military base in Jordan, escalating tensions after American forces destroyed five Iranian oil tankers. The latest exchange marks another sharp escalation in the six-month-old U.S.-Iran war, with the conflict increasingly threatening regional security and global energy supplies.

Iran said its missile strike targeted the Al-Azraq air base in Jordan, which hosts U.S. military assets. Iranian state media reported that the operation damaged maintenance and repair facilities, aircraft deployment areas and shelters. Those damage claims could not immediately be independently verified. Jordan’s military said it intercepted 18 ballistic missiles launched from Iran toward the kingdom. No casualties were immediately reported.

The Iranian attack came after U.S. forces destroyed five Iranian oil tankers on Tuesday. The U.S. military said the crews were ordered to abandon the vessels before they were struck. The operation followed an Iranian attack targeting a U.S. Navy warship. Iranian officials had previously warned that American military bases in the region would be targeted if Washington attacked Iranian oil tankers.

Iran has also threatened to target oil tankers operating near U.S.-allied Kuwait and Bahrain. The threats have heightened fears of further disruption to commercial shipping across the Persian Gulf and the Strait of Hormuz.

The strategic waterway has become a major flashpoint in the conflict. Shipping through the Strait of Hormuz has fallen sharply, raising concerns about global oil and gas supplies. Reuters reported Wednesday that only six commodity vessels transited the strait on Tuesday, well below the recent average.

The escalation has also pushed oil prices higher. Brent crude approached $100 a barrel on Wednesday, while U.S. West Texas Intermediate crude traded above $94 a barrel as markets assessed the risk of further supply disruptions.

U.S. Secretary of State Marco Rubio has warned that Washington will continue responding to Iranian attacks. The latest U.S. strikes on Iranian tankers were described by American officials as retaliation for attacks on U.S. naval forces.

Iranian state media also claimed that the Revolutionary Guard had attacked two U.S. destroyers with ballistic missiles. The claim had not been independently confirmed by the U.S. military and should be treated as an Iranian claim.

The latest confrontation comes as both sides remain locked in a wider struggle over control of the Strait of Hormuz, a vital route for global energy shipments. With Iran threatening further attacks on shipping and U.S. forces continuing operations against Iranian assets, concerns are growing that the conflict could expand further across the Middle East and place additional pressure on global energy markets.

WASHINGTON DC — The United States and Iran exchanged attacks around the strategically vital Strait of Hormuz, sharply escalating tensions after the U.S. military struck three Iranian oil tankers following Iranian missile attacks on American Navy vessels.

The U.S. Central Command said American forces targeted three Iranian crude-oil carriers on Saturday after Iran’s Islamic Revolutionary Guard Corps launched ballistic missiles toward two U.S. Navy ships. No American personnel were reported injured in the attacks.

The strikes targeted vessels including a tanker near Iran’s Kharg Island, a major hub for the country’s oil exports. The escalation has raised fresh concerns about the security of commercial shipping through the Strait of Hormuz, one of the world’s most important energy corridors.

Iran subsequently claimed that its forces struck an unmanned U.S. vessel attempting to enter the Strait of Hormuz. The United States had not immediately confirmed the Iranian claim, according to The Associated Press.

Iranian authorities have also threatened further action against vessels they consider to be using unauthorized routes in the region. The exchange of attacks comes as military tensions between Washington and Tehran continue to intensify following the collapse of an earlier ceasefire.

The Strait of Hormuz is a critical global energy chokepoint, and disruption there could have consequences far beyond the Middle East. Shipping traffic through the waterway has already fallen significantly amid the conflict, while oil markets remain highly sensitive to developments in the region.

The latest confrontation also comes as OPEC+ prepares to meet Sunday. The group is expected to maintain its current oil-production policy amid continuing disruption to energy exports through the Strait of Hormuz.

The situation remains fluid, with both sides issuing competing claims about attacks on vessels. Independent confirmation of some Iranian military claims was not immediately available.

WASHINGTON — The United States military said Saturday that it struck three Iranian crude-oil tankers after Iran’s Islamic Revolutionary Guard Corps (IRGC) launched ballistic missiles toward two U.S. Navy warships operating in the region. U.S. Central Command (CENTCOM) said a U.S. aircraft carrier and a guided-missile destroyer successfully evaded multiple Iranian attacks. No American personnel were injured, according to the command.

CENTCOM said U.S. forces permanently disabled the M/T Downy off the coast of Iran’s Kharg Island and the M/T Stark 1 near Jask. American forces also destroyed the unladen M/T Kylo, also known as the Noxen, in the Gulf of Oman after the crew was directed to abandon the vessel, according to CENTCOM. The U.S. military said the three tankers were part of what it described as a multibillion-dollar “shadow network” allegedly used to finance the IRGC and its regional proxies.

“Let the message to the IRGC be clear,” CENTCOM Commander Adm. Brad Cooper said. “If you shoot at two of our ships, we will impose an even higher economic cost.” Cooper added that the United States would continue defending its forces and, if necessary, could target Iran’s oil fleet.

Iran condemns the strikes

Iran has condemned the U.S. attacks and warned that continued attacks on Iranian vessels could lead to further military retaliation. The strikes represent a significant escalation in the confrontation between Washington and Tehran, particularly because they directly target Iranian oil shipping. One of the attacks occurred near Kharg Island, Iran’s major oil-export hub.

The latest exchange of fire also raises concerns about the security of commercial shipping and energy supplies in and around the Strait of Hormuz, one of the world’s most strategically important oil-shipping routes.
