DUBAI/DORAL, Florida – Iran’s military warned U.S. forces on Monday not to enter the Strait of Hormuz after President Donald Trump said the United States would start helping to free ships stranded in the Gulf by the U.S.-Israeli war on Iran.
Trump gave few details of the plan to aid ships and their crews that have been “locked up” in the vital waterway and are running low on food and other supplies more than two months since the conflict began.
“We have told these Countries that we will guide their Ships safely out of these restricted Waterways, so that they can freely and ably get on with their business,” Trump said in a post on his Truth Social site on Sunday.
The unified command of Iran’s armed forces responded by warning U.S. forces to stay out of the strait.
Its forces would “respond harshly” to any threat, it added, telling commercial ships and oil tankers to refrain from any movement in the absence of coordination with Iran’s military.
“We have repeatedly said the security of the Strait of Hormuz is in our hands and that the safe passage of vessels needs to be coordinated with the armed forces,” Ali Abdollahi, the head of the forces’ unified command said in the statement.
“We warn that any foreign armed forces, especially the aggressive U.S. army, will be attacked if they intend to approach and enter the Strait of Hormuz.”
U.S. Central Command said it would support the effort with 15,000 military personnel, more than 100 land and sea-based aircraft, along with warships and drones.
“Our support for this defensive mission is essential to regional security and the global economy as we also maintain the naval blockade,” Admiral Brad Cooper, the CENTCOM commander, said in a statement.
Hundreds of ships and as many as 20,000 seafarers have been unable to transit the strait during the conflict, the International Maritime Organization says.
Soon after Trump’s comments, the United Kingdom Maritime Trade Operations agency said a tanker had reported being hit by unknown projectiles in the strait.
The agency said all crew were reported safe in the incident, which occurred 78 nautical miles north of Fujairah, in the United Arab Emirates, but few details were immediately available.
Iran has been blocking nearly all shipping from the Gulf apart from its own for more than two months, sending energy prices soaring.
Some vessels attempting to transit the strait have reported being fired on, and Iran seized several other ships. Last month, the U.S. imposed its own blockade of ships from Iranian ports.
The Trump administration has been seeking help from other countries to form an international coalition to secure shipping in the strait. CENTCOM said the latest effort would combine “diplomatic action with military coordination.”
It was not immediately clear which countries the U.S. operation would aid or how the operation would work. It will not necessarily include U.S. Navy ships escorting commercial ships, Axios reporter Barak Ravid said in a post on X.
The White House did not immediately respond to a request for comment.
