Trump's Claim and Lack of Evidence

President Donald Trump said on Sunday that Iran's Kharg Island oil hub is "being blown to smithereens," posting a one-line message on his Truth Social platform accompanied by an AI-generated video clip. "Kharg Island being blown to smithereens!!! President DJT," he wrote, without offering further details. Reuters confirmed the video was most likely synthetically generated, using software that detects AI-manipulated imagery. Several hours after the post, there was no evidence that Kharg, Iran's main oil export terminal, had been attacked. The White House and the Defense Department did not immediately respond to Reuters requests for comment outside regular business hours, and there was no immediate response to Trump's post in Iranian media.

Kharg Island handled 90% of Iran's oil exports before the war launched by S. and Israeli attacks on February 28, according to multiple reports. An attack on the island would severely disrupt Iran's energy trade and put huge pressure on its economy, analysts have noted. Iran is OPEC's third-largest producer.

Escalation After Months of Quiet

The post came hours after the two countries traded attacks for the first time since late July, following weeks of stepped-up S. economic sanctions against Tehran. A S. official said forces attacked two Iranian launchers on Larak Island, about 660 kilometers east of Kharg. The official said Islamic Revolutionary Guard Corps forces were observed preparing to launch rockets with sea mines into the Strait of Hormuz. S. Central Command said it took "limited, precise" action against minelaying forces posing an "imminent threat."

In retaliation, Iran launched ballistic missiles at two S. bases in Jordan, according to Iranian media. Jordan's state television said its armed forces intercepted eight missiles that entered its airspace. A Fox News reporter, citing a S. source, said nearly all incoming missiles had been intercepted at that point. Iran's Revolutionary Guards said the attack killed and wounded several soldiers and citizens and vowed a "response and punishment" from Tehran, according to Iranian state media. The Iranian foreign ministry said the Jordan strikes targeted S. bases used to launch and support the attack on Larak.

Iran's army also said it struck the United Arab Emirates' Al Minhad air base early on Monday with drones, targeting sites where S. forces and helicopters were stationed, in response to the Larak attack. The Revolutionary Guards used air defense missiles to shoot down a S. drone that crashed in Gulf waters, the Mehr news agency reported.

Strait of Hormuz Disruptions

The renewed conflict has affected shipping through the Strait of Hormuz, a waterway that carried nearly a fifth of global crude oil and liquefied natural gas shipments before it was blockaded in the six-month-old war. Visible commodity vessel traffic fell to five vessels per day over the weekend, according to shipping data. The actual number could be higher because some vessels have switched off automatic identification systems to evade attacks.

Iran state TV said a supertanker caught fire and was brought to a halt after being struck by two naval mines in the southern Strait of Hormuz, citing a Revolutionary Guards statement. The Guards said the vessel had been attempting to pass through the waterway illegally, but gave no details of the ship or crew.

Last week, Trump said all mines had been detonated or removed from international waters of the strait, and warned that any vessel placing new mines would be destroyed. Iran's Revolutionary Guards' navy called Trump's statements "an obvious lie" and reiterated that the strait remained closed to ships without Iranian permission.

Escalating Economic Pressure

The latest military exchanges came as the Trump administration shifted toward economic pressure on Tehran. Treasury Secretary Scott Bessent told Reuters on Sunday that new secondary sanctions were likely to be unveiled weekly, with an initial focus on banks.

"We're starting with the banks, and we're telling the banks it's not okay to have Iranian money and to aid the regime," Bessent said. He added, "You're going to see a lot more of these every week," and said the next step may be cutting off an institution entirely from the dollar-based financial system. On Friday, the Treasury imposed penalties on United Arab Emirates branches of Egypt's Banque Misr over alleged financial links to Iran.
