The US will not lift its blockade on Iranian ports until a deal has been reached with Tehran, US President Donald Trump has said, amid continuing uncertainty over whether fresh talks to end the war will take place.
The blockade, which began a week ago, is absolutely destroying Iran, Trump wrote on his social media platform Truth Social, adding his country was winning the conflict by a lot.
His comments come with the temporary US-Iran ceasefire set to end on Wednesday, but with no certainty over whether a second round of peace talks will go ahead in Pakistan.
There is tightened security in Pakistan's capital in anticipation of a meeting. But US Vice President JD Vance - set to lead the US delegation - has not yet left Washington, while Iran says it has not decided whether to attend.
Since the blockade began, US forces have directed 27 vessels to turn around or return to an Iranian port, according to US Central Command (Centcom). The US also intercepted and seized an Iranian-flagged cargo ship for the first time in the conflict, after it tried to get through the blockade on Sunday.
Tehran deemed it an act of piracy and a violation of the fragile ceasefire between the two countries. Iran has maintained its own blockade on the Strait of Hormuz for nearly two months - causing global energy prices to soar.
Trump said Iran had decided to fire bullets and called it a total violation to the ceasefire agreement. Iran said it would keep the route shut until the US stopped the blockade of its ports.
There are indications a second round of peace talks between the US and Iran will go ahead, despite Tehran refusing to confirm whether it will send a delegation. Following the first round of talks earlier this month, US Vice-President J D Vance said the US could not get to a situation where the Iranians were willing to accept our terms, and Iran's foreign ministry urged Washington to refrain from excessive demands and unlawful requests.
The potential second round comes at a crucial moment. Sources told the BBC on Monday afternoon that the US delegation would be leaving soon but did not specify a time, while officials told the New York Times that they would depart on Tuesday.
Later on Monday, an Iranian foreign ministry spokesperson said that, so far, Tehran had no plans to attend. Vance is expected to be joined by special envoy Steve Witkoff and Trump's son-in-law and adviser, Jared Kushner, as in the previous round of talks. It is not clear who - if anyone - from Iran's side will be showing up. However, in Islamabad, there are signs of preparation for the talks.
Guests at the city's Serena Hotel, where the previous round was held, have been told to leave in preparation for meetings, while police announced the closure of key roads due to the arrival of foreign delegations.
A senior government official told Reuters news agency that Pakistan was confident it could get Iran to attend the talks.
