US forces engaged several Iranian boats in the Strait of Hormuz on Monday as part of efforts to help ships move through the vital waterway, officials say.
Iran’s parliamentary speaker, Mohammad Bagher Ghalibaf, responded with a strong message to Washington.
“We have not even started yet,” he said, according to reports from Tehran.
The incident took place as President Donald Trump launched “Project Freedom”.
This operation aims to guide neutral vessels safely through the strait amid ongoing tensions.
US Central Command reported that helicopters took part in action against small Iranian boats that threatened commercial shipping.
American forces also turned away missiles and drones aimed at navy and merchant ships.
Admiral Brad Cooper, head of US Central Command, said the steps helped open a passage.
Two US-flagged merchant vessels successfully crossed the area on the first day of the operation.
Iran has disputed the US account and accused American forces of violating a recent ceasefire.
Tehran claims some of the vessels involved were civilian boats carrying goods.
The country maintains it will defend its position in the strait, a critical route for global oil supplies.
This latest exchange comes after earlier US-Iran strikes earlier this year that led to a fragile pause in hostilities.
Both sides now appear keen to show strength while avoiding full escalation.
Defence Secretary Pete Hegseth described the American moves as temporary and necessary to protect shipping.
“We’re not looking for a fight,” he noted.
The situation has raised concerns about possible disruption to energy markets.
Shipping companies watch developments closely, as any further incidents could affect insurance costs and routes through the Gulf.
For now, the focus remains on keeping the strait open for neutral traffic while the two governments exchange firm words.
