US President Donald Trump said Sunday that Washington will continue talks with Iran despite what he described as violations of a ceasefire agreement in the Strait of Hormuz, while also issuing a stark warning that the United States could strike major Iranian infrastructure if negotiations collapse.

In a post on Truth Social, Trump said US representatives would travel to Islamabad, Pakistan, for talks with Iranian negotiators, even after recent maritime incidents involving vessels in the strategic waterway. He described the American proposal now on the table as “very fair and reasonable” and said he hoped Tehran would accept it.

At the same time, Trump threatened sweeping action if no agreement is reached, saying the United States would target Iran’s power plants and bridges.

Iranian officials were later quoted as saying they do not intend to show up in Islamabad this week so long as the US naval blockade of Iranian ports persists.

Trump’s latest warning followed reports that Iran had reimposed tight control over the Strait of Hormuz after gunboats from the Islamic Revolutionary Guard Corps Navy allegedly fired on three commercial vessels. The incidents, according to maritime security reports, ended a brief period of relative calm that had followed the declaration on April 8 of a two-week ceasefire in hostilities involving Iran, the United States, and Israel.

Trump accused Iran of breaching that ceasefire, saying shots had been fired in the strait at vessels including a French ship and a British freighter. Despite that, he indicated the United States would not walk away from diplomacy.

He also argued that Iran’s reported move to close the strait would have limited practical effect because the US-led blockade was already restricting the flow of goods to the Islamic Republic. Trump said such a move would hurt Iran economically more than the United States, framing the disruption as a self-inflicted blow to Tehran.
