Dubai: The United States will launch an effort on Monday to “guide” stranded ships from the Iran-gripped Strait of Hormuz, President Donald Trump said, as two ships around the strait reported attacks.

Trump gave few details about what could be a sweeping attempt to help hundreds of vessels and some 20,000 seafarers. Iran quickly denounced the move as a ceasefire violation.

Trump said in a social media post on Sunday that “neutral and innocent” countries have been affected by the Iran war, and “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.”

“Project Freedom” would begin on Monday morning in the Middle East, Trump said, adding that his representatives are having discussions with Iran that could lead to something “very positive for all.”

U.S. Central Command said the initiative would involve guided-missile destroyers, more than 100 aircraft and 15,000 service members. The Pentagon did not immediately answer questions about how they would be deployed.

Ships and seafarers, many on oil and gas tankers and cargo ships, have been stuck in the Arabian Gulf since the war began. Crew members have described to The Associated Press seeing intercepted drones and missiles explode over the waters as their vessels run low on drinking water, food and other supplies. Many sailors come from India and other countries in South and Southeast Asia.

“They are victims of circumstance,” Trump wrote, and described the effort as a humanitarian gesture “on behalf of the United States, Middle Eastern Countries but, in particular, the Country of Iran.” But he sounded a warning: “If, in any way, this Humanitarian process is interfered with, that interference will, unfortunately, have to be dealt with forcefully.”

Iran’s state-run IRNA news agency called Trump’s announcement part of his “delirium,” and Ebrahim Azizi, head of the national security commission of Iran’s parliament, said on X that any interference in the strait would be seen as a ceasefire violation.

Trump spoke hours after Iran said it was reviewing the U.S. response to its latest proposal to end the war and made clear these are not nuclear negotiations. The fragile three-week ceasefire appears to be holding.
