Trump did not indicate in a social media post on Sunday which officials the US would send to a second round of face-to-face talks with Iran in Islamabad.
The White House and the office of US Vice President JD Vance, who led the first round of talks, did not immediately respond to messages on Sunday morning (Sunday evening AEST).
In his post, Trump accused Iran of violating the ceasefire agreement by firing bullets into the Strait of Hormuz on Saturday and threatened to destroy civilian infrastructure in Iran if the country does not agree to the deal offered by the US.
“If they don’t, the United States will shut down every power plant and bridge in Iran,” Trump wrote.
