A senior Iranian lawmaker has dismissed US President Donald Trump’s plan to escort ships through the Strait of Hormuz, calling it unrealistic.

Ebrahim Azizi, head of the Iranian parliament’s foreign policy and national security commission, also warned that any US involvement in enforcing a new maritime arrangement in the waterway would violate the ceasefire.

Ebrahim Azizi made the remarks in a social media post.

He said any American interference in the Strait’s new regulatory framework would be viewed as a violation of the truce, adding that the waterway “would not be managed” by statements from Washington.

The comments came after Trump announced that US forces would begin escorting commercial vessels through the strategic passage from Monday, amid ongoing restrictions that have disrupted maritime traffic since the US and Israel launched attacks on Iran in late February.

Trump described the initiative, dubbed “Project Freedom,” as a humanitarian effort aimed at assisting ships and crews stranded in the crucial waterway.

He also warned that any attempt to obstruct the operation would be met with a forceful response.

Details of how the plan would be implemented and which countries would be involved remain unclear.

Iran has imposed tight controls on shipping in the Strait of Hormuz during the conflict, requiring vessels to seek prior approval before transit.

Iranian officials maintain the measures are within the country’s sovereign rights to ensure security, while denying that the strait has been fully closed.

Tehran has also said it will not permit vessels linked to its adversaries or their allies to leave the Gulf without authorisation.

At the same time, the United States has enforced its own naval restrictions on Iranian ports, a move Tehran has described as illegal and a violation of a ceasefire reportedly brokered by Pakistan earlier in April.

Iranian officials have repeatedly criticised the blockade, warning that any attempt to challenge its control of the strait through military means would trigger a strong response.
