U.S.-led task force tells ships to reroute on first day of new effort to reopen the Strait of Hormuz

The center warned that passing close to the usual routes, known as the traffic separation scheme, “should be considered extremely hazardous due the presence of mines that have not been fully surveyed and mitigated.”

The U.S.-led maritime task force’s announcement marked the start of the effort to revive traffic and restore confidence among commercial vessels transiting the strait. It risked unraveling the fragile ceasefire that has held even without progress on the issues that sparked the war launched by the U.S. and Israel on Feb. 28.

It was unclear as of Monday morning whether any vessels had accepted the U.S. offer and Iran’s military command told state broadcaster IRIB on Monday that ships passing must coordinate with them.

“We warn that any foreign military force — especially the aggressive U.S. military — that intends to approach or enter the Strait of Hormuz will be targeted,” Major General Pilot Ali Abdollahi said.

The disruption of the waterway through which roughly one‑fifth of the world’s oil typically passes has become one of the most enduring consequences of the war. It continues to squeeze countries that depend on Persian Gulf supplies and added new volatility to energy prices for households and businesses worldwide.

Moves to resolve the war, which likely would a plan to return traffic to prior levels, are still in proposal and review phase, with no negotiations between the U.S. and Iran underway.

New standoff over the Strait of Hormuz

Announcing the ship shepherding effort in a social media post Sunday, Trump promised “neutral and innocent” 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.”

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 answer questions about how they would be deployed.

Neither U.S. officials nor Trump said whether “Project Freedom” would include military escorts through the Iran-controlled strait, leaving an element of risk for any tempted to chance it. The uncertainty has deterred ships and insurers from exercising their freedom of navigation and testing the route, despite earlier U.S. pushes to restart traffic.

Seafarers, many on oil tankers or cargo ships, have been stuck in the Persian Gulf since the war began, describing 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.

“They are victims of circumstance,” Trump wrote, describing the effort as a humanitarian gesture “on behalf of the United States, Middle Eastern Countries but, in particular, the Country of Iran.”

Trump also sounded a warning: “If, in any way, this Humanitarian process is interfered with, that interference will, unfortunately, have to be dealt with forcefully.”

As more ships reported coming under attack Sunday, Iran’s state-run IRNA news agency called Trump's announcement part of his “delirium.” 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.

Iran reviews US response to latest proposal

Tehran is reviewing the U.S. response to its latest proposal to end the war, Iran’s judiciary Mizan news agency cited Foreign Ministry spokesman Esmail Baghaei saying Sunday.

But “at this stage, we have no nuclear negotiations,” Baghaei said. Iran’s nuclear program and enriched uranium have long been the central issue in tensions with the U.S., but Tehran would rather address it later.

Iran’s proposal wants other issues resolved within 30 days and aims to end the war rather than extend the ceasefire, according to Iran’s state-linked media. Trump on Saturday said he was reviewing the proposal but expressed doubt it would lead to a deal.

Iran’s 14-point proposal calls for the U.S. lifting sanctions on Iran, ending the U.S. naval blockade of Iranian ports, withdrawing forces from the region and ceasing all hostilities, including Israel’s operations in Lebanon, according to the semiofficial Nour News and Tasnim agencies, which have close ties to Iran's security organizations.

Iran stands firm

Iranian officials have vowed the strait won't return to its prewar conditions and moved to impose charges on transiting ships, but the U.S. has warned shipping companies they could face sanctions for paying Iran in any form.

The U.S. naval blockade since April 13 is depriving Tehran of oil revenue it needs to shore up its ailing economy. The U.S. Central Command on Sunday said 49 commercial ships have been told to turn back.

“We think that they’ve gotten less than $1.3 million in tolls, which is a pittance on their previous daily oil revenues,” U.S. Treasury Secretary Scott Bessent told Fox News on Sunday, adding that Iran's oil storage is rapidly filling up and "they’re going to have to start shutting in wells, which we think could be in the next week.”
