The White House said in a statement that, in light of the president's announcement that he was extending the ceasefire and awaiting a proposal from Iran, Vance and the US negotiating delegation would not be travelling to Pakistan on Tuesday.

The White House did not offer any additional updates on the possibility of in-person meetings. US President Donald Trump said Tuesday he is extending the ceasefire with Iran at Pakistan's request while awaiting a "unified proposal" from Tehran, even as the U.S. military maintains its blockade of Iranian ports.
