The Strait of Hormuz remains in a state of disruption after a weekend of escalations that saw ships come under gunfire, a US seizure of an Iranian-flagged vessel, and mounting confusion over transit rules. Commercial movement through the critical oil route has turned chaotic, with vessels reversing course, drifting near the chokepoint, or attempting passage amid conflicting instructions and warnings.
The latest flashpoint, including Washington’s first interception of a vessel since enforcing a naval blockade, has added a new layer of direct confrontation at sea, even as reports of ships being targeted and turned back raise fresh doubts over whether the route is effectively open.
With the ceasefire set to expire in days, the combination of maritime clashes, diplomatic uncertainty and rising military threats has pushed the situation in Hormuz back to the brink, leaving one of the world’s most vital energy corridors functioning, but under severe strain.
US seizure of Iranian vessel adds to escalation
Tensions intensified further after US forces intercepted and seized the Iranian-flagged cargo ship Touska in the Gulf of Oman. Washington said the vessel ignored repeated warnings and attempted to breach a naval blockade, prompting US forces to disable it before boarding.
Tehran has condemned the move as “maritime piracy” and a violation of the ceasefire, warning of a response. The seizure marks a shift toward more direct confrontation between the two sides at sea, threatening the fragile ceasefire that is officially set to expire on Wednesday.
Indian tankers under fire
The fragility of passage through Hormuz was laid bare over the weekend when two India-flagged vessels came under gunfire while attempting to cross the strait.
Oil tanker Sanmar Herald and bulk carrier Jag Arnav were targeted by Iranian Revolutionary Guard Corps gunboats on Satursday. At least one vessel sustained minor damage, including a shattered window, though no injuries were reported.
A widely circulated distress call from the Sanmar Herald captain captured the confusion unfolding at sea. “You gave me clearance to go… you are firing now. Let me turn back,” the captain said, highlighting conflicting instructions and the sudden escalation faced by commercial vessels.
The incident disrupted a convoy of 14 India-bound ships carrying crude, LPG and fertilisers. Thirteen vessels were forced to halt or turn back at different points, with several now drifting near Larak Island awaiting fresh clearance.

India lodges protest as safety concerns rise
India formally raised the issue with Tehran, summoning Iranian envoy Mohammad Fathali and conveying “deep concern” over the targeting of its vessels.
Foreign Secretary Vikram Misri urged Iran to ensure the safety of merchant shipping and resume facilitating passage for India-bound ships. Tehran has said it will convey the concerns to its authorities, but no immediate change in ground conditions has been reported.
The incident underscores the risks faced by commercial shipping as geopolitical tensions spill directly into maritime routes.
'No more Mr nice guy!' says Trump
As the ceasefire expiry nears, Trump on Sunday said an American delegation would travel to Islamabad for a fresh round of talks with Iran, even as he issued one of his strongest warnings yet to Tehran.
“My representatives are going to Islamabad, Pakistan. They will be there tomorrow evening, for negotiations,” Trump said in a post on Truth Social.
At the same time, he signalled a harder line, saying Washington had already put forward a “very fair and reasonable deal” and would act if it was rejected. “No more Mr nice guy!” he said, warning that the US could target Iran’s critical infrastructure, including power plants and bridges, if negotiations failed.
The remarks underscore the dual-track approach adopted by the US, combining a renewed diplomatic push with overt military pressure as the ceasefire deadline approaches.
The upcoming outreach follows an earlier round of US–Iran talks in Islamabad on April 11 that ended without a breakthrough after nearly 21 hours of negotiations. The discussions, mediated by Pakistan, stalled over key sticking points, including Iran’s nuclear programme and sanctions relief.
Washington has pushed for limits on uranium enrichment and long-term assurances against nuclear weapons development, demands that Tehran has rejected, insisting its programme is for civilian purposes and that such conditions infringe on its sovereignty.
With positions still far apart and tensions escalating at sea, the latest warning adds to uncertainty over whether diplomacy can hold.
Transit becomes unpredictable
Shipping through Hormuz has become highly unstable. While one India-linked tanker, Desh Garima, managed to pass through, most vessels are facing severe disruption.
Multiple ships, including Sanmar Herald, Desh Vaibhav, Desh Vibhor and Jag Arnav, were forced to turn back near the chokepoint. Others remain stranded or drifting as operators await clarity on whether transit is permitted.
Maritime agencies further reported that vessels are receiving mixed signals, with some cleared for passage and others warned away or fired upon. The result is a growing backlog across the Persian Gulf and near paralysis of normal traffic flows.
Given that about one-fifth of global oil and gas passes through this corridor, even partial disruption is enough to strain supply chains and unsettle energy markets.
Ceasefire uncertain as violations and mistrust grow
The already fragile ceasefire is now under severe strain ahead of its expiry. The weekend incidents, including the ship seizure and attacks on commercial vessels, have deepened mistrust between Washington and Tehran.
Iranian officials have accused the US of acting in bad faith, while the US continues to justify its actions as enforcement of a blockade. The widening gap raises the likelihood that the truce may not hold.
Casualties from the broader conflict remain high across the region, adding urgency to efforts to avoid renewed fighting.
Talks in Pakistan uncertain amid rising tensions
Diplomatic efforts are also faltering. The US has said negotiators will head to Pakistan for another round of talks, but Iran denied any reports of them participating.
Iranian state media has already cast doubt on the talks taking place. The latest escalation at sea has further complicated the prospects for dialogue, even as mediators attempt to keep channels open.
Energy and security risks intensify
With the Strait of Hormuz unstable, global energy markets are facing renewed uncertainty. Ships are idling, rerouting or waiting for clearance, while industry players warn of potential supply disruptions if the crisis deepens.
Military assessments have also grown more severe, with the security situation in the Gulf described as critical. Increased naval activity, warning shots and vessel damage have heightened the risk of miscalculation in an already volatile region.
Thus, the Strait of Hormuz is not fully closed, but as of now it not functioning as a dependable trade route. The weekend’s tanker attacks, the US ship seizure and stalled diplomacy have pushed the ceasefire to the brink.
