The guided-missile destroyer USS Spruance fired rounds from its 5-inch gun into the engine room of an Iranian-flagged cargo ship Sunday after the vessel ignored six hours of warnings and attempted to breach the U.S. naval blockade in the Gulf of Oman, the first confirmed use of force since the blockade began on April 13. Marines boarded and seized the ship, identified as the Touska, and it remains in American custody.
President Trump announced the encounter on Truth Social Sunday afternoon, writing that the Touska "tried to get past our Naval Blockade, and it did not go well for them." U.S. Central Command released video that evening showing the escalation from verbal warnings to disabling fire, confirming every material detail in the president's account.
The seizure marks a sharp escalation at a moment when diplomacy and deterrence are running on parallel tracks, and the clock is ticking. A ceasefire between the two sides is set to expire midweek, Iranian state media says Tehran has "no plans" to join the next round of talks, and Iran's military command is openly threatening retaliation. For the first time since the blockade went into effect, the United States has shown it will back its demands with live fire.
CENTCOM's account, reported by Breitbart News, laid out the sequence in detail. The Touska was sailing toward Iran's Bandar Abbas port when the Spruance began issuing warnings. Those warnings continued for six hours. The crew did not comply.
Audio from the CENTCOM video captured the final command before the shooting started:
"Motor vessel Touska, motor vessel Touska, vacate your engine room, vacate your engine room. We are prepared to subject you to disabling fire."
The Spruance then fired several rounds from its MK 45 gun, a standard naval deck weapon, directly into the Touska's engine compartment, disabling the vessel's propulsion. Marines from the 31st Marine Expeditionary Unit boarded and secured the ship. Trump said they were "seeing what's on board."
The Washington Examiner noted that Trump said the Touska was under U.S. Treasury sanctions, adding a legal dimension to the interdiction beyond the blockade itself. No information about the cargo or any casualties aboard the vessel has been released.
Before Sunday's confrontation, U.S. officials said at least 25 vessels had turned back from the blockade zone without incident. The Touska was the first to refuse.
Iran's response was swift and hostile. The Khatam al-Anbiya Central Headquarters, the command structure overseeing Iran's armed forces, accused the United States of "armed piracy" and warned that Iranian forces would "soon respond and retaliate" for the strike and boarding. IRGC-linked outlets carried the statement.
That threat came on the same day Iranian President Masoud Pezeshkian warned during a call with Pakistani Prime Minister Shehbaz Sharif that U.S. actions suggest Washington may seek to "betray diplomacy." Iran's official IRNA news agency cited what it described as Washington's "unreasonable and unrealistic demands," "constant contradictions," and continued enforcement of the blockade as reasons there was "no clear prospect for fruitful negotiations."
The blockade itself went into effect April 13, after Pakistan-mediated talks collapsed. Washington's demands reportedly include the reopening of the Strait of Hormuz, where Iran had reimposed shipping restrictions. Tehran has rejected the U.S. conditions as "nonstarters."
Iranian state media reported Sunday that Tehran had "no plans" to participate in the next round of negotiations, a direct challenge to the diplomatic track the administration has been pursuing alongside the naval pressure campaign.
The Touska seizure capped a volatile 48 hours of conflicting signals from both sides. On Friday, Trump said a deal could be reached "within a day or two." By Sunday morning, he told Axios in a phone call that "the concept of the deal is done" and there was a "very good chance" an agreement could be completed.
Hours later, the Spruance opened fire.
U.S. officials said Vice President JD Vance is expected to travel to Islamabad to lead the next round of talks, joined by envoy Steve Witkoff and senior adviser Jared Kushner. Pakistan held back-to-back calls Sunday with senior Iranian officials and reiterated its role as a facilitator between the two sides.
But Iran's willingness to sit down remains an open question. The ceasefire is set to expire midweek, and no date for the next round of talks has been confirmed. The New York Post reported that the incident was part of broader U.S. pressure tied to sanctions enforcement and rising tensions, a framework that leaves little room for ambiguity about American intent.
The Wall Street Journal reported Saturday, before the Touska encounter, that the U.S. military was already preparing to board and seize additional Iran-linked vessels in international waters. That report now reads less like a warning and more like a preview.
Trump did not leave Tehran guessing about what comes next. He stated Sunday that if Iran does not accept a deal, the United States could target "every single Power Plant, and every single Bridge" in the country. The language was direct, public, and left no diplomatic cushion.
That threat sits alongside the military's demonstrated willingness to enforce the blockade with force. The recent degradation of Iran's naval capabilities has already reshaped the balance of power in the region. Sunday's encounter showed that the blockade is not symbolic.
Newsmax confirmed that the Touska was the first interception since the blockade began, calling the incident a direct test of American resolve. CENTCOM's own account, with its detailed timeline of warnings, escalation, and boarding, suggests the military was prepared for exactly this scenario and executed it by the book.
Iran now faces a choice it has spent weeks trying to avoid. The blockade is real. The firepower behind it is real. The ceasefire is running out. And the diplomatic off-ramp Tehran has dismissed as a collection of "nonstarters" may be the only alternative to an escalation the regime cannot win.
The narrow defeat of a House resolution to end the Iran campaign showed that congressional support for the administration's approach, while thin, held. That margin may matter more now than it did a week ago.
Several important questions remain unanswered. No details about the Touska's cargo have been released. Whether anyone aboard was injured or killed has not been disclosed. The specific legal authorities under which the blockade operates have not been publicly cited. And the exact date of the ceasefire deadline, described only as "midweek", has not been pinned down.
What is known is that Iran's remaining naval assets and its willingness to test the blockade will determine whether Sunday's encounter was an isolated incident or the opening chapter of something larger.
For years, the foreign-policy establishment insisted that maximum pressure would provoke Iran into reckless escalation. On Sunday, it was an Iranian cargo ship that tried to run a blockade, and the U.S. Navy that responded with precision, patience, and exactly as much force as the moment required.
