A senior Iranian shipping official announced on Saturday, 3 October 2026 that Iran will take the United States to international courts over the seizure of its container ship Touska, an incident that reportedly occurred on 19 April in the Gulf of Oman — during an active ceasefire between Tehran and Washington. The announcement signals a significant diplomatic and legal escalation in an already fraught bilateral relationship.

What Happened to the Touska

Mohammad-Reza Modarres Khiabani, Chief Executive Officer of the Islamic Republic of Iran Shipping Lines, described the incident as a 'war crime' at a meeting in Tehran. According to his account, US Navy forces boarded the Iranian-flagged vessel Touska off the coast of Chabahar port in southeastern Iran, struck the ship's engine room, and took 28 crew members hostage. Khiabani alleged that the vessel was carrying medicines for the Iranian Red Crescent Society and supplies for dialysis patients at the time of seizure.

Iran's Legal Position

Khiabani argued that boarding and seizing a commercial vessel during an active ceasefire constitutes both a 'war crime and violation of the truce.' He further stated that any form of naval blockade violates international law and amounts to a 'hostile' act. Iran has indicated it will formally pursue the matter through international judicial mechanisms, though the specific courts or bodies it intends to approach have not yet been named publicly. This is not the first time Iran has threatened or pursued legal action against Washington at international forums — Tehran has previously filed suits at the International Court of Justice (ICJ) over sanctions and asset freezes.

Trump's Remarks on Iran

Meanwhile, US President Donald Trump declined to outline his administration's next steps on Iran, speaking to reporters at the White House before departing aboard Marine One. Asked directly about his next move, Trump said the situation was 'working out very well' and predicted the conflict would not last long. 'That's very, oh, it's — well, if I told you, you'd have a major story, right? But you'll see. Working out very well. Iran is not doing well,' Trump said, without elaborating on specific actions or timelines. He also referenced Iran while discussing global energy supplies and efforts to increase European diesel availability.

Broader Context and What It Means

The Touska seizure, if confirmed as described by Iranian officials, would represent a rare instance of military action against a commercial vessel during an officially acknowledged ceasefire period. Notably, the incident took place in the Gulf of Oman — a strategically critical waterway adjacent to the Strait of Hormuz, through which a significant share of global oil supplies transit. Critics argue that if Iranian claims about the ship's humanitarian cargo are accurate, the seizure raises serious questions under international maritime and humanitarian law. The US government has not issued a detailed public response to Iran's characterisation of the incident. How international courts respond to a potential Iranian filing could set a precedent for the legal boundaries of ceasefire enforcement at sea.

What Happens Next

Iran's pursuit of international legal remedies is likely to unfold over months or years, given the timelines typical of international judicial proceedings. The fate of the 28 crew members reportedly detained remains a key humanitarian flashpoint. Trump's cryptic remarks suggest the US administration is weighing further steps regarding Iran, though the nature and timing of any action remain unclear. All eyes will be on whether Washington offers an official account of the Touska incident and whether the ceasefire framework between the two countries holds amid mounting legal and diplomatic pressure.
