The United States military announced Tuesday it had eliminated 16 Iranian mine-laying vessels near the Strait of Hormuz as Operation Epic Fury entered its 11th day, with Defense Secretary Pete Hegseth declaring it the most intense day of strikes against Iran since the war began on February 28. The announcement came amid growing concern over the fate of the world's most critical oil shipping corridor and a sharp exchange of threats between Washington and Tehran over who controls access to it.

U.S. Central Command released the figure alongside unclassified footage of some of the vessels, confirming that the minelayers were among multiple Iranian naval assets taken out during Tuesday's operations. The Pentagon separately said it had also struck Iranian mine storage facilities. Joint Chiefs Chairman Gen. Dan Caine said the U.S. military has now sunk more than 50 Iranian ships since the start of the war, describing the effort as making "substantial progress toward destroying the navy" and adding that the hunt for mine-laying vessels would continue.

"We're crushing the enemy in an overwhelming display of technical skill and military force," Hegseth told reporters at a Pentagon briefing. "Today will be yet again our most intense day of strikes inside Iran. The most fighters. The most bombers. The most strikes."

The Minelayer Threat and the Strait

The strikes on the mine-laying vessels followed a tense sequence of social media exchanges in which President Donald Trump said he had no reports of Iran actually deploying explosives in the Strait of Hormuz, but warned that if mines were placed, he wanted them "removed, IMMEDIATELY." Trump initially said the U.S. had "completely destroyed" 10 inactive mine-laying vessels, with Central Command later revising the number upward to 16.

"Additionally, we are using the same technology and missile capabilities deployed against drug traffickers to permanently eliminate any boat or ship attempting to mine the Hormuz Strait. They will be dealt with quickly and violently," Trump wrote on social media. "BEWARE!"

The strait, roughly 21 miles wide at its narrowest point, is the passage through which approximately 20 percent of the world's traded oil and natural gas normally flows. Since the start of the war, shipping traffic through the channel has effectively halted. Iran's paramilitary Revolutionary Guard declared it would "not allow the export of even a single liter of oil from the region to the hostile side and its partners until further notice." A senior Revolutionary Guard official had previously stated that Iran would fire on any vessel attempting to pass.

The economic stakes were substantial. Saudi Aramco President and CEO Amin Nasser confirmed that tankers were being rerouted to avoid the strait, and that the company's east-west pipeline would reach its full capacity of 7 million barrels per day flowing to the Red Sea port of Yanbu. "The situation at the Strait of Hormuz is blocking sizable volumes of oil from the whole region," he said. "If this takes a long time, that will have serious impact on the global economy."

Market Response and the Reinsurance Play

Oil prices remained volatile throughout the day but retreated from the near-$120-a-barrel peak hit earlier in the week. Brent crude ended the day down more than 5 percent at $88.03 a barrel after Trump suggested on Monday that the war could end "soon." West Texas Intermediate dropped more than 7 percent to around $84 a barrel.

The S&P 500 fell 0.2 percent Tuesday as investors continued to monitor developments in the strait. One energy analyst described the market outlook as "binary" — either the strait reopens and the risk premium unwinds sharply, or it stays shut and the world faces what he called "the largest supply disruption in modern history."

The Trump administration moved to provide financial cushion for the shipping industry, with the U.S. International Development Finance Corp. announcing $20 billion in rolling reinsurance to cover shipping companies operating in the Gulf against financial losses tied to the conflict. The U.S. Navy has so far declined to provide direct escorts for commercial tankers, with officials citing unacceptable risk levels, despite Trump's public statements that such escorts were available whenever needed. White House press secretary Karoline Leavitt acknowledged Tuesday that no escorts had yet occurred while calling them "an option."

Casualties and the War's Broader Toll

Tuesday's operations unfolded as the Pentagon disclosed the full scope of non-fatal U.S. casualties for the first time since the war began. About 140 American service members have been wounded, Pentagon spokesman Sean Parnell said in a statement, adding that "the vast majority" of those injuries were minor and that 108 had already returned to duty. Eight service members remain severely injured. Seven Americans have been killed.

Caine told reporters that U.S. forces have now struck more than 5,000 targets inside Iran since the operation began. Iran's ballistic missile attacks have declined 90 percent since the opening days of the war, and one-way drone strikes have fallen by 83 percent, according to the Pentagon. U.S. bombers have dropped "dozens" of 2,000-pound GPS-guided penetrating weapons on deeply buried missile launchers in Iran's south, and several Iranian drone manufacturing facilities have been destroyed.

The broader human toll continues to grow across the region. At least 1,230 people have been killed in Iran, more than 480 in Lebanon, and 11 in Israel, according to officials in those countries. In Lebanon, where Israel resumed major strikes after Hezbollah launched rockets at Israel on March 2, the death toll has climbed steadily, with the U.N. refugee agency reporting that more than 667,000 people had registered as displaced — an increase of over 100,000 in a single day — and that more than 85,000, mostly Syrians, had crossed into neighboring Syria.

Iran's Defiance and International Pressure

Iranian leaders offered no signals of a shift in posture. Parliament Speaker Mohammad Bagher Qalibaf wrote on social media that Iran was "definitely not looking for a ceasefire." Ali Larijani, a top security official, posted a warning addressed to Trump on the same platform, stating that "even those bigger than you couldn't eliminate Iran." Iran's Revolutionary Guard issued its own statement, saying it alone would "determine the end of the war" and dismissing Trump's comments about a quick conclusion as "nonsense."

Germany's foreign minister, visiting Jerusalem — the first European ministerial visit to Israel since the war began — assessed that Tehran was "not ready for a diplomatic solution."

G7 leaders scheduled an emergency videoconference for Wednesday to address the energy consequences of the conflict, with France — which holds the rotating G7 presidency — confirming that the talks would focus on the energy situation and potential measures to soften its global economic impact. The International Energy Agency held its own emergency meeting of member states earlier the same day to assess oil supply security and weigh a coordinated release of emergency petroleum reserves.
