Trump Navy Seizes Iranian Ship in First Forcible Blockade Action as Tehran Threatens Retaliation

President Donald Trump announced Sunday that U.S. Navy forces had forcibly seized an Iranian cargo vessel after "blowing a hole in the engineroom" to disable it, marking the most aggressive enforcement action yet under Washington's naval blockade of Iran.

The dramatic encounter unfolded in the Gulf of Oman when the USS Spruance, a guided-missile destroyer, intercepted the Iranian-flagged vessel Touska as it attempted to breach the U.S. blockade. Trump confirmed on Truth Social that "U.S. Marines have custody of the vessel" and are "seeing what's on board."

Six-Hour Standoff Leads to Forcible Action

Video released by U.S. Central Command captured the tense hours-long confrontation, showing repeated warnings issued to the Iranian crew. The audio reveals stark commands: "Vacate your engine room... we are prepared to subject you to disabling fire."

According to CENTCOM, the Touska ignored multiple warnings over a six-hour period while sailing toward Iran's Bandar Abbas port. Only after exhausting diplomatic options did U.S. forces resort to disabling fire using the destroyer's 5-inch MK 45 gun, targeting the vessel's engine compartment to stop its advance.

Marines from the 31st Marine Expeditionary Unit subsequently boarded and secured the vessel, which remains in U.S. custody. The seizure represents the first known forcible interdiction since the blockade took effect April 13, though officials say at least 25 other vessels have voluntarily turned back.

Iran Threatens "Soon" Retaliation

Tehran's response was swift and furious. Iran's Khatam al-Anbiya Central Headquarters condemned what it called "armed piracy" and warned that Iranian forces would "soon respond and retaliate" for the strike and boarding.

State-affiliated Iranian media claimed Iranian forces had already launched drone attacks against U.S. naval assets in response, though these assertions remain unverified. The escalatory rhetoric from both sides threatens to derail already fragile ceasefire negotiations.

Diplomatic Talks Hang in Balance

The naval confrontation comes as critical ceasefire talks face an uncertain future. Despite Trump expressing optimism earlier Sunday, telling Axios that "the concept of the deal is done" with a "very good chance" of completion, Iran quickly undercut that timeline.

Iranian state media reported there were "no plans" to participate in the next round of talks, citing Washington's "unreasonable and unrealistic demands" and "constant contradictions." Tehran specifically pointed to the continued enforcement of the naval blockade as evidence that negotiations lack "clear prospect for fruitful negotiations."

Vice President JD Vance is expected to lead the next round of talks in Islamabad alongside envoy Steve Witkoff and senior adviser Jared Kushner, but Iran's apparent withdrawal casts doubt on their prospects.

Core Demands Remain Unresolved

At the heart of the diplomatic impasse are fundamental U.S. demands that Iran reopen the Strait of Hormuz, halt uranium enrichment, and surrender its stockpile of highly enriched uranium. Tehran has consistently rejected these conditions as "nonstarters."

The volatile 48-hour period saw Trump initially suggest a deal could be reached "within a day or two," only for Iran to reimpose shipping restrictions through the strategic waterway and resume hostile actions against commercial vessels.

Pressure Campaign Intensifies

U.S. officials signal they're prepared to escalate further. A Wall Street Journal report indicates the military is preparing to board and seize additional Iran-linked vessels as part of a broader pressure campaign targeting Tehran's oil exports and supply networks.

Trump himself has issued explicit warnings, stating Sunday that if Iran refuses a deal, the United States could target "every single Power Plant, and every single Bridge" in the country.

Critical Deadline Approaches

With the fragile ceasefire set to expire midweek, the seizure of the Touska has placed negotiations under renewed strain. Both sides now appear to be signaling readiness to escalate rather than compromise.

Pakistan, serving as mediator, held back-to-back calls Sunday with senior Iranian officials in an attempt to bridge the widening gaps, but the diplomatic window appears to be rapidly closing.

The forcible seizure represents a significant escalation in the standoff and raises questions about whether either side remains committed to finding a negotiated solution before the ceasefire expires.
