The aim is to "re-establish the freedom of commercial shipping to pass through the Strait of Hormuz," the US military wrote on X on Monday night, local time in Sweden.
Donald Trump announced on Sunday evening that the country would, "to the best of its ability," help "vessels and crews safely get through the strait," in a post on Truth Social.
The president said that these were ships from countries around the world, "most of which are not involved in the Middle East conflict."
Iran immediately responded that it would consider any American interference a violation of the ceasefire.
“The Strait of Hormuz and the Persian Gulf will not be governed by Trump's unrealistic statements,” wrote Ebrahim Azizi, head of the National Security Commission in Iran, on X.
