Donald Trump has ordered US navy forces in the Strait of Hormuz to 'shoot and kill' any Iranian boats caught laying sea mines, he announced on Thursday on his Truth Social platform, in a move that throws fresh uncertainty over a shaky ceasefire in the Iran war and deepens a crisis already reverberating through global markets.
The escalation came after nearly two weeks of an uneasy truce between Washington and Tehran, a ceasefire that Trump himself had said he would extend indefinitely while insisting there was 'no time frame' for ending the conflict. That pause was fragile even on paper.Iran seized two commercial vessels in the Straiton Wednesday and fired on a third Liberian‑flagged ship, according to shipping companies and maritime security sources, even as US forces maintained a de facto blockade on traffic in and out of Iranian ports.
The latest twist began with a pair of characteristically blunt posts from Donald Trump on Thursday afternoon, first reported at 14:01 BST.
'I have ordered the United States Navy to shoot and kill any boat, small boats though they may be (Their naval ships are ALL, 159 of them, at the bottom of the sea!), that is putting mines in the waters of the Strait of Hormuz,' the US president wrote on Truth Social.
He went on to say there should be 'no hesitation,' confirming that American mine‑clearing vessels were already operating in the Strait. 'Additionally, our mine 'sweepers' are clearing the Strait right now,' he added. 'I am hereby ordering that activity to continue, but at a tripled up level!'
None of this has yet been translated into a published Pentagon rules‑of‑engagement document, so for now the order exists in the slightly surreal space of presidential social media, backed by real firepower in one of the world's most sensitive waterways. There has been no independent confirmation of Iranian boats actively laying mines at the precise moment of his order, so his language should be read as a standing instruction rather than a response to a specific, verified incident.
A separate post saw Donald Trump claim that the US was now in 'total control' of the Strait of Hormuz and that 'no ship can enter or leave without the approval of the United States Navy.' If taken literally, that would amount to the United States asserting gatekeeper status over a key international strait used for global trade, something the UN's maritime agency has previously said no country has a legal right to do.
The news came after theUS military announced the previous Monday that it would block shipping in and out of Iran's ports. Commanders have not publicly specified the exact line of the cordon, but US Central Command says that, since the start of the blockade, it has ordered 27 vessels to turn around or return to Iranian harbours.
Matters escalated sharply on Sunday whenUS forces attacked and seized an Iranian‑flagged cargo ship, the M/T Majestic X, in the Gulf of Oman. In a statement posted on X on Thursday, Central Command said American forces carried out a 'maritime interdiction and right‑of‑visit boarding' of the stateless vessel, which it said was transporting oil from Iran in the Indian Ocean.
'We will continue global maritime enforcement to disrupt illicit networks and interdict vessels providing material support to Iran, wherever they operate,' the statement read. 'International waters cannot be used as a shield by sanctioned actors. The Department of War will continue to deny illicit actors and their vessels freedom of maneuver in the maritime domain.'
