Donald Trump rejected Tehran’s move, saying Iran could not “blackmail” Washington by shutting down the strategic waterway, which carries a significant share of the world’s oil and gas supply.

Tehran said its actions were in response to an ongoing US blockade of Iranian ports, which it described as a violation of the ceasefire agreement. Mojtaba Khamenei warned that Iran’s navy was prepared to deliver “new bitter defeats” to its adversaries.

Shipping sources reported that at least two vessels came under fire while attempting to transit the strait, highlighting the growing risks to maritime traffic. India summoned Iran’s ambassador in New Delhi after two Indian-flagged ships were reportedly targeted, expressing serious concern over the incidents.

Iran’s Supreme National Security Council said the country’s control over the strait includes requiring ships to pay for security, safety, and environmental protection services.

State media also reported that the United States had presented new proposals following Pakistan-mediated talks in recent days. Tehran is reviewing the proposals but has not yet issued a formal response.

Despite earlier remarks from Trump suggesting imminent negotiations, there were no immediate signs of direct US-Iran talks over the weekend. The US president, however, said discussions with Iran were “very good,” while accusing Tehran of attempting to shut the strait again.
