Iran’s military warned US 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 US-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 for 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 US forces to stay out of the strait.

Iran’s 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.

“Any foreign armed forces, especially the aggressive US army, will be attacked if they ⁠intend to approach and enter the Strait of Hormuz,” he warned.

Abdollahi accused the US military of engaging in “piracy and banditry” in international waters, which he claimed threatens global trade and economic stability.

The general also emphasised that Iran would not tolerate any foreign interference and would respond forcefully to any threats or acts of aggression.

“The resistant and courageous Iranian nation, along with its armed forces, will respond to any provocation with a severe and regret-inducing retaliation,” he declared.

The commander also warned commercial vessels and tankers to avoid transiting the Strait without prior coordination with Iranian forces, stressing that failure to do so could jeopardise their safety.

He further cautioned the US’s allies to avoid taking any actions that could escalate tensions in the region.

Following Trump’s announcement, US 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.
