Three seafarers killed in Hormuz strike as UN warns of widening fallout in International Shipping News 13/06/2026 The latest strike, which the United States said had been carried out as part of its blockade enforcement operations, involved the Palau-flagged tanker MT Settebello near the coast of Oman. Tit-for-tat strikes by the US and Iran following the apparent suspension of negotiations to end the war threaten to accelerate, with President Trump on social media promising to hit Iran “very hard” and “assume total control of their oil and gas markets.” The UN Secretary-General is “deeply concerned” by the continuing escalation, his spokesperson said in a statement on Thursday. António Guterres urged all parties to return to the full implementation of the ceasefire and warned that any further deterioration could trigger “a full resumption of the conflict, with unpredictable consequences for the region and the world, especially the most vulnerable countries.” Attacks ‘simply unacceptable’ According to UN maritime agency, the latest incident brings the number of confirmed seafarer fatalities to 14 since the crisis began on 28 February. The agency has verified 46 attacks on international shipping in and around the Strait of Hormuz during that period. International Maritime Organization (IMO) Secretary-General Arsenio Dominguez strongly condemned the attack, calling them “simply unacceptable.” “I strongly condemn any act from any party that endangers the lives of seafarers and the safety of international shipping,” he said. Under pressure Beyond the immediate loss of life, the UN maritime agency warns that thousands of civilian seafarers remain exposed to mounting risks. Across the wider Gulf region, roughly 20,000 seafarers are estimated to remain aboard commercial and offshore vessels. IMO says many are operating under sustained security threats and severe psychological pressure, while some crews remain detained by parties to the conflict. A global food security risk’
