US forces seized an Iranian-flagged cargo ship near the Strait of Hormuz on Sunday as diplomatic efforts to extend a fragile ceasefire intensified, escalating tensions in a maritime corridor critical to global energy supplies and Horn of Africa trade routes.
President Donald Trump said the ship Touska was warned by a US Navy guided missile destroyer to stop, but its "crew refused to listen." Trump added that the US Navy "stopped them right in their tracks by blowing a hole in the engine room" and that US Marines now have custody of the vessel, "seeing what's on board."
Iran condemned the seizure as a ceasefire violation, with a Khatam al-Anbiya spokesperson warning: "We warn that the armed forces of the Islamic Republic of Iran will soon respond and retaliate against this armed piracy by the US military."
The escalation comes as Vice President JD Vance leads a US delegation to Islamabad on Monday for renewed talks with Iran aimed at extending a ceasefire set to expire Wednesday evening. The diplomatic push follows an initial round of rare face-to-face discussions last weekend, with Pakistani Foreign Minister Ishaq Dar positioning his country as a mediator seeking to "bridge differences" between Washington and Tehran.
However, prospects for breakthrough remain uncertain. While senior Iranian official Mohammed Bagher Qalibaf signaled cautious openness to diplomacy despite "significant gaps" between the two sides, Tehran has not formally confirmed the meeting.
The standoff centers on the Strait of Hormuz, a chokepoint through which roughly one-fifth of global oil supply typically flows. Iranian officials have taken an increasingly firm position, with Iran's Speaker of Parliament Mohammad Bagher Qalibaf declaring: "It is impossible for others to pass through the Strait of Hormuz while we cannot."
Commercial shipping remains severely disrupted due to overlapping measures: Iranian threats to restrict passage and a US-led blockade targeting vessels linked to Iranian ports that has been in place since April 13. Trump has said the US blockade "will remain in full force" until Tehran reaches a deal with Washington.
The shipping crisis has already triggered broader regional consequences. Iranian forces reportedly fired on two India-flagged merchant ships, forcing them to retreat and prompting a diplomatic protest from New Delhi. After a brief uptick in transit attempts Saturday, vessels in the Gulf again stayed put following reports of ships coming under fire mid-passage.

The Strait of Hormuz disruption poses particular risks for Horn of Africa economies heavily dependent on fuel imports through Red Sea routes. Ethiopia imports virtually all petroleum products through the corridor connecting the Red Sea to the Gulf of Aden, with shipments typically transiting through Djibouti port. Previous Red Sea shipping disruptions have affected fuel availability in Ethiopia during a recent fuel shortage crisis, when supply constraints and price spikes occurred across the country.
The Pakistan-mediated talks represent a diplomatic opportunity as the Wednesday ceasefire deadline approaches. The US delegation, including Vice President Vance alongside envoys Steve Witkoff and Jared Kushner, faces the challenge of bridging what Iranian officials describe as significant gaps on core issues.
Major sticking points persist, including Iran's nuclear enrichment program, regional alliances, and control over the Strait of Hormuz. Recent developments suggest little movement toward compromise, with Iran acknowledging receipt of new US proposals but giving no indication of a shift in stance.
Pakistani Foreign Minister Dar has confirmed contact with Iran's Foreign Minister Abbas Araghchi as Islamabad ramps up security preparations for the talks. The broader conflict, now entering its eighth week, has killed according to reports from multiple parties thousands across Iran, Lebanon, Israel, and neighboring regions.
For Iran, restricting access to the strait represents powerful leverage over global energy markets and US allies. For Washington, maintaining the blockade serves as economic pressure on Tehran. The ship seizure Sunday suggests both sides remain committed to escalatory tactics even as diplomatic channels remain open.
The ceasefire expires Wednesday evening, with talks scheduled to continue in Islamabad as commercial shipping remains disrupted in one of the world's most critical energy chokepoints.
