The International Maritime Organization reports that around 20,000 seafarers are trapped in the Persian Gulf following the strait's closure, leading to widespread distress. Multiple reports indicate these individuals are experiencing severe mental health impacts, including stress, mental breakdowns, and feelings of being overwhelmed. According to reports, at least six cruise ships are captive in the area, including MSC Euribia with 6,000 passengers, exacerbating the scale of the crisis.
The immediate humanitarian situation is dire, with many seafarers refusing to sail through the Strait of Hormuz due to safety concerns. The International Transport Workers' Federation has received about 1,000 inquiries from seafarers on 300 vessels since the conflict started, with about 20% seeking repatriation. This region has been classified as a 'war zone' by the maritime sector, granting enhanced rights to seafarers, including repatriation at the shipowner's expense. IMO Secretary-General Arsenio Dominguez has expressed concern over the increased risk and significant mental strain on affected seafarers, while the IMO has begun work on developing a framework for evacuation.
Specific vessels are heavily impacted, with between 50 and 55 French-flagged or French-owned ships blocked in the Persian Gulf, according to French transport minister Philippe Tabarot. MSC Croisières plans to charter five flights to repatriate 1,000 passengers from MSC Euribia. Celestyal Cruises has ended its winter season in the Gulf by canceling four cruises, and German shipping company Hapag-Lloyd said it is continuing to avoid the strait while monitoring conditions. Swedish Stena Bulk has 'fewer than a handful' of ships stuck in the Persian Gulf, according to Erik Hånell of Stena Bulk, and reports indicate the U.S.-flagged tanker Stena Imperative was damaged by Iranian gunfire in Bahrain in early March.
Violence and safety incidents persist, with seven incidents involving ships recorded in the zone since the start of strikes against Iran, resulting in several casualties among seafarers. Several ships began moving toward the strait after reports of opening, then turned back due to reports of ships being fired upon. At least 14 vessels reversed course within 72 hours of enforcement, according to shipping data cited by Reuters, highlighting the ongoing dangers.
Maritime traffic in the Strait of Hormuz has collapsed, with an estimated 90% decrease from usual flow. Uncertainty continues over whether the strait is open or closed, with conflicting reports from the U.S. and Iran. Some operators resumed transit under tighter controls, while others delayed departures, rerouted cargo, or held vessels outside the strait, according to multiple reports.
The overall outlook for talks wasn’t particularly positive.
This crisis unfolds against a backdrop of a fragile ceasefire that is holding but set to expire soon. A two-week ceasefire in the war mediated by Pakistan and announced on 8 April gives some hope to this track. However, the conflict continues to exhibit dynamics of escalation, with both the U.S.-Israel coalition and Iran facing incentives to widen and deepen the confrontation.
Internationally, France is trying to form a coalition to protect ships in the region amid the war involving Iran, Israel, and the U.S., as stated by French transport minister Philippe Tabarot. According to Tabarot, eight additional French ships are stuck in the Red Sea. The International Maritime Organization said it was working to verify whether the reopening complies with international law and freedom of navigation standards.
Diplomatic efforts are underway, with a second round of negotiations between the United States and Iran expected to take place in Islamabad, Pakistan in the coming days. President Donald Trump says a U.S. delegation is heading for talks with Iran in Pakistan, and the American team is taking shape, with reports indicating it includes JD Vance, Steve Witkoff, and Jared Kushner. Reports also indicate the Iranian delegation includes Mohammad Bagher Ghalibaf and Abbas Araghchi, but there is as yet no official confirmation from Iran that negotiations will take place.
Conflicting Iranian signals on participation in talks add to the uncertainty. The Iranian state-affiliated Fars News Agency said a final decision on whether Iran would take part in the second round of negotiations 'could not yet be confirmed or ruled out.' IRIB, the main Iranian state media, reported that Iran’s participation in the talks had not yet been confirmed by Iranian officials. According to Fars, sources inside Iran described the overall outlook for talks as not 'particularly positive,' and another source stated that as long as the US maritime blockade continues, Iran won’t even consider a second meeting in Islamabad. Iranian sources told CNN an Iranian team would arrive in Pakistan on Tuesday, but the semi-official outlet Tasnim reported that Iran has no current plan to send a negotiating delegation and said there would be no talks while the US continues to impose a maritime blockade on Iranian ports.
Escalatory rhetoric has intensified, with President Trump stating on 30 March that the U.S. was in discussions with the Iranian regime for the urgent reopening of the strait, and threatening widespread devastation and the destruction of Iran’s power infrastructure if this goal is not reached. The Iranian response to the ultimatum – amplified by Mehr News – showed a map of power plants in Saudi Arabia, the United Arab Emirates, Qatar, and Kuwait as potential targets for retaliatory attacks. Ebrahim Azizi, the head of the Iranian parliament’s national security committee, said that the key trading route for international oil exports leading through the Strait of Hormuz would not be reopened for American vessels. The committee instead approved a toll on ships, with Iran currently charging vessels around £1.5 million to transit the strait.
As long as the US maritime blockade continues, Iran won’t even consider a second meeting in Islamabad.
Iranian claims of reopening clash with U.S. enforcement of a blockade. Iran said the Strait of Hormuz was 'completely open' to commercial vessels during a temporary ceasefire announced Friday, and Iranian Foreign Minister Abbas Araqchi said Friday in a post on X that vessels could again transit the strait along coordinated routes during the ceasefire. However, U.S. warships continued blocking ships tied to Iranian ports during the ceasefire, and reports indicate American warships, aircraft, and more than 10,000 personnel continued enforcing restrictions on vessels tied to Iranian ports. Officials framed the operation as a targeted effort to choke off Iran’s maritime trade without fully closing the strait, allowing non-Iran-bound traffic to continue moving through.
Iranian conditions and control over strait transit remain strict. Iranian officials said vessels must follow designated transit routes and, in some cases, coordinate passage with the Islamic Revolutionary Guard Corps. According to Lieutenant-Colonel Ebrahim Zolfaghari, the Islamic Republic of Iran, in line with previous agreements and with good faith during negotiations, had agreed to a managed passage of a limited number of oil tankers and commercial ships through the Strait of Hormuz. A spokesperson stated that control of the Strait of Hormuz has returned to its previous state, and this strategic strait is under the intense management and control of the armed forces, adding that as long as the United States does not fully end the disruption to the free passage of vessels originating from Iran to their destinations and from destinations back to Iran, the situation will remain under severe control.
Reactions to ceasefire and reopening announcements have been mixed. On Friday, Foreign Minister Abbas Araghchi announced the reopening of the strait following the implementation of a ceasefire in Lebanon. Reports indicate the Islamic Republic had identified the ceasefire as an indivisible part of a 10-point proposal it had forwarded prior to Trump's announcement. Reacting to the announcement, Trump took to his Truth Social platform, alleging that Iran had 'agreed to never close the Strait of Hormuz again.' Trump claimed that the United States' 'naval blockade will remain in full force and effect as it pertains to Iran, only, until such time as our transaction with Iran is 100% complete,' and said that ceasefire negotiations 'should go very quickly and that most of the points are already negotiated.' Iran has categorically refuted Trump's claims, asserting that the strait was only open to commercial vessels, which would be allowed to transit through only a designated route and with Iran’s authorization.
Implications for Iran's military strategy and conflict dynamics are significant. Reports indicate the IRGC has sufficient stockpiles in its arsenal to extend the conflict further, and its mosaic defence strategy organizes the state’s defensive units into multiple regional and semi-independent layers to make Iran’s command system difficult to dismantle. According to official statements, the regime is convinced that it has shown that the United States is incapable of destroying Iran’s nuclear or missile programmes.
Key unknowns persist, including the exact number of passengers stranded in the Persian Gulf, as reports vary between 15,000 and implied counts from nearly 2,000 ships. The specific details and casualty counts of the recent maritime incidents in the zone remain unclear, with sources mentioning seven incidents with casualties but providing conflicting specifics. It is also uncertain whether Iran will officially confirm its participation in the negotiations in Pakistan, given conflicting reports from Iranian sources, and how long the fragile ceasefire will hold, with conditions for its extension or breakdown not fully defined. The full extent of the mental health crisis among stranded seafarers and what specific support measures are being implemented have not been detailed.
