US President Donald Trump says he will extend the ceasefire with Iran until talks between the two countries have progressed. He added that the blockade of Iranian ports will remain in place until Tehran presents what he called a "unified proposal." Iran has attacked three cargo ships in the Strait of Hormuz, according to Iranian reports, after Trump said he was extending the ceasefire.

The status of the talks remains unclear. US Vice President JD Vance did not depart for Islamabad as expected on Tuesday, while Iran has yet to officially respond to Trump's remarks. Meanwhile, an adviser to Iran's parliamentary speaker dismissed the ceasefire extension, saying it "means nothing" and describing it as "a ploy to buy time for a surprise strike."
