In the latest chapter of the intensifying 2026 Strait of Hormuz crisis, the United States military has boarded and seized multiple Iranian-linked tankers attempting to evade a U.S. naval blockade, even as President Donald Trump announced an indefinite extension of the ceasefire with Iran. This move comes amid a flurry of ship seizures and firings in the strategically vital waterway, which carries roughly 20% of the world's seaborne oil trade. The Strait of Hormuz, a narrow 34-kilometer-wide passage between Iran and Oman, has become a flashpoint since late February, when U.S. and Israeli airstrikes triggered Iran's retaliatory closure and attacks on commercial vessels.
Tensions reached a boiling point on April 22, 2026, when Iran's Revolutionary Guard Corps (IRGC) fired upon and seized two container ships—the Panamanian-flagged MSC Francesca and the Liberian-flagged Epaminondas—in the strait, hours after Trump's ceasefire announcement. A third vessel, the Panamanian-flagged Euphoria, was also targeted but managed to escape with damage. These actions underscore the fragile state of the truce, with both sides accusing the other of violations while commercial shipping grinds to a near halt.
🔥 Trump's Ceasefire Extension Amid Ongoing Blockade
President Trump extended the ceasefire indefinitely on April 22, stating it would remain in place until Iran submits a 'unified proposal' for peace talks mediated through Pakistan. 'The blockade scares them even more than the bombing,' Trump remarked in a Fox News interview, emphasizing economic pressure over military action. However, the U.S. naval blockade of Iranian ports, imposed on April 13, continues unabated. U.S. Central Command (CENTCOM) reports turning back over 30 vessels, primarily oil tankers bound for or from Iran, in the past 24 hours alone.
The blockade targets ships calling at Iranian ports, preserving freedom of navigation for others, but Iran views it as a direct breach. Iranian President Masoud Pezeshkian tweeted, 'Breach of commitments, blockade and threats are main obstacles to genuine negotiations.' White House Press Secretary Karoline Leavitt countered that Iranian seizures of non-U.S. ships do not violate the truce, calling them 'piracy.'
US Military Boardings: Key Tanker Seizures Detailed
US forces have conducted several high-stakes boardings of Iranian-linked tankers in recent days. On April 19, the USS Spruance fired upon and seized the Iranian-flagged cargo ship Touska in the Gulf of Oman after it attempted to bypass the blockade. Earlier seizures include the MT Tifani, Deep Sea, Dorena, Sevin, Derya, and Majestic X—all intercepted en route to destinations like China and India. These operations involve U.S. Marines rappelling from helicopters onto decks, disabling engines if necessary, and securing vessels for diversion.
Trump ordered the Navy to 'shoot and kill any boat' laying mines or choking the strait on April 23, escalating rules of engagement amid reports of IRGC fast boats harassing traffic. No casualties from U.S. boardings have been reported, but the actions have drawn Iranian condemnation as 'piracy.'
Iran's Retaliatory Strikes and Seizures
Iran's IRGC has responded aggressively, firing on three ships on April 22 and seizing two for lacking 'permits' and tampering with navigation systems. The Epaminondas suffered bridge damage, but crews remain safe and anchored off Iran's coast. Iran has also imposed tolls exceeding $1 million per ship during brief openings, collecting revenue from over 300 transits since March.
Since the crisis began, Iran has attacked 21 commercial vessels, causing at least 15 deaths and numerous abandonments. Tactics include missiles, drones, sea drones, mines, and VHF warnings. Parliamentary Speaker Mohammad Bagher Ghalibaf stated the U.S. blockade makes reopening the strait 'impossible.'
Historical Context: From Airstrikes to Blockade
The crisis erupted on February 28 with Operation Epic Fury—U.S.-Israeli airstrikes assassinating Supreme Leader Ali Khamenei and targeting nuclear sites. Iran closed the strait, launching over 30 attacks on ships by mid-April. A temporary April 8 ceasefire saw Iran charge tolls, but failed Islamabad talks led to the U.S. blockade on April 13. Traffic plummeted from 130 ships daily to under 10.
- Feb 28: Strait closure, first ship strikes (Skylight, MKDVYOM).
- Mar 11: Peak attacks (Mayuree Naree, One Majesty).
- Apr 8: Temporary opening with tolls.
- Apr 13: U.S. blockade begins.
- Apr 22: Latest seizures post-ceasefire extension.
Economic Fallout: Oil Prices Soar Above $100
Oil prices have surged past $102 per barrel for Brent crude as of April 23, up over 7% in recent sessions due to strait disruptions. This equates to a 10% global supply cut, with U.S. gasoline averaging $4 per gallon nationally—up 59% since crisis onset. Analysts warn of $150/barrel if prolonged, rivaling 1970s shocks.
