Iran has issued a warning to the United States, indicating serious consequences for the Pentagon’s sinking of an Iranian warship off the coast of Sri Lanka using a torpedo.

“The U.S. has committed an atrocity at sea, 2,000 miles from Iran’s coastline,” Iranian Foreign Minister Abbas Araghchi stated on Thursday morning. “Mark my words: The U.S. will deeply regret the precedent it has set.”

Araghchi noted that the Iranian frigate IRIS Dena was “a guest of India’s navy” and around 130 sailors were “attacked in international waters without prior notice.” IRIS stands for Islamic Republic of Iran Ship, which is used to identify Iranian naval vessels.

The warship had participated in a naval exercise in the Bay of Bengal.

According to Sri Lankan officials, over 80 Iranian sailors lost their lives, more than 30 were injured, and the remaining are unaccounted for. Search-and-rescue operations are ongoing.

Sri Lanka’s Minister of Health Nalinda Jayatissa reportedly informed parliament on Thursday that another Iranian vessel was sailing near Sri Lanka’s territorial waters. “We are taking necessary steps to resolve this issue, mitigate the threat to lives, and ensure regional security,” he said.

Defense Secretary Pete Hegseth hailed the torpedo incident as a display of U.S. military prowess.

“An American submarine sank an Iranian warship that thought it was safe in international waters,” he told reporters at the Pentagon on Wednesday. “Instead, it was sunk by a torpedo. A silent demise.”

Joint Chiefs of Staff Gen. Dan Caine described the operation as “an outstanding demonstration of America’s global reach” and pointed out it was the first time an American torpedo had sunk a ship since World War II.

“Hunting, locating, and eliminating an out-of-region deployer is something only the United States can accomplish on this scale,” he remarked.

According to the U.S. Central Command, the warship is one of over 20 Iranian ships “struck or sunk to the ocean floor” by American forces.

Despite President Donald Trump claiming earlier in the week that some senior Iranian officials had reached out, Iran continued to launch retaliatory attacks.

The Iranian Revolutionary Guard Corps announced it had targeted a U.S. oil tanker in the northern Persian Gulf on Thursday.

Several tankers anchored in the Gulf after the IRGC warned that any U.S., Israeli, or European tanker passing through the critical Strait—situated between the Persian Gulf and the Gulf of Oman, through which about a fifth of global oil production flows—would “certainly be attacked,” as per [source].

With traffic in the Strait of Hormuz mostly halted, global oil and gas prices soared, shipping costs skyrocketed, and many insurers withdrew war risk coverage. American consumers are likely to feel the impact soon.

Noam Raydan, a senior fellow at the Washington Institute for Near East Policy, told TIME, “This is a severe disruption.”

She added, “For numerous ships, if they transit Hormuz, they’ll do so without coverage, meaning any incident—attack, oil spill—would be their responsibility. Companies simply won’t—and shouldn’t—take that risk.”

Iran appears to have targeted several oil tankers in the Strait and energy infrastructure in Gulf nations as part of its retaliatory measures since the U.S. and Israel launched military action against the country on Saturday morning, in initial strikes.

The conflict has now involved several other countries and territories, with no immediate end in sight.

“We are ensuring Iran cannot swiftly rebuild or reconstitute its combat capabilities,” Caine told reporters on Wednesday, specifying that the U.S. military operation—dubbed Operation Epic Fury—would continue.

So far, six American service members in the region have been killed in Iranian retaliatory strikes. Trump referred to the fallen troops as “true American patriots.”

Meanwhile, there is growing concern that the Iran conflict is depleting—vital sophisticated military equipment needed to protect American bases, ships, and allies worldwide throughout the year.

There are fears it may hinder the U.S.’ ability to assist Ukraine in its defense against Russia.

“I am deeply worried about Ukraine,” Sen. Richard Blumenthal of Connecticut, a Democrat on the Senate Armed Services Committee, told TIME. “Plainly, our resources are limited, and I think we’ll eventually struggle to provide Ukraine with what it needs.”

However, White House press secretary Karoline Leavitt asserts the U.S. “has more than enough capacity not only to successfully carry out Operation Epic Fury but to go much further.”

She told TIME on Wednesday, “We have weapon stockpiles in locations unknown to many in the world.”
